GSLL is no longer dependent on cl-utilities, so remove it. Generic function #'name needs to be loaded before the obsolete-gsl-version condition is defined, otherwise CLISP complains. Conditionalize away a couple more 64 bit tests that were overlooked.

New directory "calculus" to hold numerical-differentiation, numerical-integeration, and monte-carlo. Converted some return array arguments in BLAS to optional arguments. Define a condition 'obsolete-gsl-version to use in #'complete-definition. Try to incorporate cygwin into init.lisp; needs testing by a cygwin user.

By sending the two parts of a complex as separate doubles (complex double-float), or packing the two parts into a one double-float argument (complex single-float), it is possible to pass complex numbers in GSL function calls. This is very likely to be non-portable, so a test is conducted and the results in *pass-complex-scalar-as-two-reals* determine whether defmfun does this translation or just creates a function that signals an error. The complex tests have been modified so that no longer expect an error: SBCL 64: TOTAL: 1223 assertions passed, 5 failed, 0 execution errors. CCL 64: TOTAL: 1228 assertions passed, 0 failed, 0 execution errors. This also works in 32 bit SBCL.

Removed declaration of 'indexed-functions as ignorable in #'with-defmfun-key-args, which now lets SBCL compile with no warnings of any kind. Superficial attempt at modernizing simulated-annealing so that it compiles, but it still fails.

Combination #'copy-to-destination had permutation instead of combination. Only :compile-toplevel in eval-when for maref-function-picker to prevent warning messages. Non-symmetric eigenvalues-eiegenvectors-nonsymm now return both eigenvalues and eigenvectors; this function evidently doesn't support set-parameters-nonsymmetric so that has been removed.

Redefine #'copy so that it has one required argument (source) and one optional argument (destination). For marrays, create a destination using make-marray, if one was not given, and then use the memcpy functions to fill the values. For all other mobjects, copy will copy objects by calling one of two generic functions, #'copy-to-destination and #'copy-making-destination, depending on whether a destination was supplied. The former is defined if a GSL _memcpy function exists. The latter will look for a GSL _clone function, then make a CL instance with the pointer returned as mpointer. If there is no clone function, it will attempt to make a new object using make-load-form, so will fail if that method has not been defined. Added a check to defmfun that signals an error if a variable is used in the C arguments other than top-level that is not used in the CL arglist. This should not happen and is usually an indication of a typo.

For permutations and combinations, rename #'validp from #'data-valid and return :success-failure rather than :boolean. In fact, it returns T or an error due to the design of the GSL functions; not clear if this is wanted on the GSL designers' part. Passes SBCL 64 test.

Added some functions introduced in GSL 1.9 to solve eigenvectors and eigenvalues for non-symmetric matrices. These are untested as yet. Changed array output for special functions to be optional arguments which can take a size (integer) and create a marray of the right size.

When used as the default optional/key argument values for arrays, the value symbol 'element-type is replaced with the actual element type for the method. This replaces the :make-marray form. When used as the default optional/key argument values for arrays, the form (eltcase element-type form element-type form ...) will be replaced by the appropriate form. This replaces the direct appending of the (element-type form element-type form) list. SBCL same tests pass.

The option :gsl-version will allow specification of when the function was introduced into GSL. If the current version preceeds that version, the defmfun compiles into an error signal. The :before option allows the placement of code to execute prior to calling the foreign function.

Optional arguments may be specified easily as functions creating GSL objects, keying off the element type of the required arguments. For example, the arglist ((matrix matrix) i &optional (vector :make-marray vector (dim0 matrix))) means that if vector is not specified, it will make a vector whose element type is the same as matrix, and whose length is the number of rows of matrix. This is used to proved default arguments for a number of functions, including the workspace argument for eigenspaces. Some arguments that were required before are now optional and therefore placed after the required arguments. Renamed to matrix-transpose from matrix-transpose-copy, and the the in-place transpose renamed to matrix-transpose* from matrix-transpose. Tests on 64 bit: SBCL: TOTAL: 1223 assertions passed, 5 failed, 0 execution errors. CCL: TOTAL: 1228 assertions passed, 0 failed, 0 execution errors.

GSL functions that operate from one corresponding array elements and then overwrite the first array, as well as those that operate on each element of an array with a scalar, are now named starting with "elt", as in "elt+"; formerely they started with "m". This is to reinforce the idea that they are not generally a mathematical solution to algebraic problems, just elementwise operations. The scalar operations (addition, multiplication) are methods of elt+ and elt* as well. Test results 64 bit: SBCL: TOTAL: 1223 assertions passed, 5 failed, 0 execution errors. CCL: TOTAL: 1228 assertions passed, 0 failed, 0 execution errors.

Eliminated the functions #'m+c, #'m*c, turning them into methods of #'m+ and #'m*, with the scalar permitted to appear either first or second. New functions #'e*, #'e/ renamed from #'m*, #'m/ to emphasize it is elementwise multiplication and division, leaving room for a matrix multiplication function #'m* at some point in the future. It is now possible to defmfun :definition :methods with 'both as the specified category. Test results 64 bit: SBCL: TOTAL: 1223 assertions passed, 5 failed, 0 execution errors.

Instead of relying on repeated and varying checks using llkp, the new function #'optional-args-to-switch-gsl-functions provides a uniform test for determining when presence/absence of optional arguments in the defmfun form require a switch between different GSL functions.

Both CLISP and SBCL fail when making arrays of 64 bit integers, despite cffi-features:no-long-long being absent for either. Therefore, conditionalize away these types in *array-element-types* on 32 bit platforms in general, and conditionalize away all the 64 bit tests as well. Separated out integer size check into types.lisp. Restored tests vector-min and vector-max which fail in SBCL for (signed-integer 8) and (signed-integer 16) for unknown reasons. Test results: 64 bit SBCL: TOTAL: 1223 assertions passed, 5 failed, 0 execution errors. 64 bit CCL: TOTAL: 1228 assertions passed, 0 failed, 0 execution errors. 32 bit SBCL: TOTAL: 1069 assertions passed, 31 failed, 0 execution errors. 32 bit CLISP: TOTAL: 1051 assertions passed, 27 failed, 5 execution errors.

After exiting the foreign call, defmfun now inserts a form to set C-invalid to nil for outputs, as well as CL-invalid to T. Conditionalize the definition of native-pointer to native, because it's only used on native implementations and its definition in CCL was causing a spurious warning. Removed defmfun expansion examples because there are plenty of examples available now. From scratch, gsll and gsll-tests compiles and runs cleanly on CCL with no warnings or errors, and all 1208 tests pass.

The function #'polynomial-solve is now directly defined with defmfun with a single required argument and two optional arguments: the answer vector-complex-double-float and the workspace, both of which default to the right thing. The returned is now the this marray instead of a list. Simplify the definition of #'invert-matrix and return the matrix-double-float instead of the CL array. All tests pass SBCL and CCL with trace.

Testing with Clozure reveals more details on the stack overflow problem than what CLISP reveals. This is fixed by using #'slot-value instead of #'cl-array in #'copy-c-to-cl and #'copy-cl-to-c. Non-complex arrays were not handled correctly in #'copy-array-from-pointer; fixed. There is a dependency of permutation and combination on the definition of #'data-class-name through defmfun. Test results: CCL: TOTAL: 1143 assertions passed, 52 failed, 3 execution errors. CLISP: TOTAL: 996 assertions passed, 149 failed, 11 execution errors. SBCL: TOTAL: 1208 assertions passed, 0 failed, 0 execution errors. (But only the second time it's run in SLIME.) Variable *print-contents* to disable printing of marray contents in print-object; this is helpful for debugging.

Make functional for non-native CL implementation, with allocation of C arrays and correct copying between CL and C sides. Testbed for this is CLISP, but CLISP has several problems which may be a problem with the GSLL code or may be in CLISP: - need to set sys::*inhibit-floating-point-underflow* - CLISP doesn't see defconstant defined when it's used in the same file - many tests give "Program stack overflow" error and debugging procedure not clear - failure on amd64 bit platform

Made the generic function #'contents-from-pointer that takes a pointer to a GSL struct and produces a list of the contents suitable for the :initial-contents argument to #'make-marray. Added an argument :from-pointer to #'make-marray that then creates a new marray with the same contents. Some functions in solve-minimize-fit return a pointer to a GSL vector with double-floats. Copying in this way is necessary because GSL has malloced the data in a non-CL place. Sometimes, this results in the copying of data whose only further use will be to extract a pointer to pass to another GSL function. Added a method to #'mpointer that permits directly passing a pointer, but this isn't useful for arrays because there are many element types so the functions have been defined as methods.

Split off the class definition for foreign-array into its own file along with applicable definitions. Make permutations and combinations direct subclasses of both foreign-array and marray, but not subclasses of vectors. All these classes now have initialize-instance :after methods that allocate and set the pointers and finalizers. All tests pass.

Fixed several errors that only were present for #-native implementations (i.e. not SBCL). It is not yet complete for non-native arrays. It now compiles completely in CLISP but crashes immediately with a SIGSEGV on amd64 platforms.

In defmobject, set the mpointer value if #'allocate is being called. For each file that defines a defmobject, I put a comment at the top showing the relevant GSL header file. For generators and quasi, the (re)initializing function returns void and not an :int, so that is changed in the defmobject definition, which now permits a list of two elements in initialize-suffix, with the second element indicating the :c-return.

All GSL objects are full CL objects with garbage collection. There is no need to manually free the associated memory. All objects may be assigned in the normal CL way, e.g. let, so there is not #'letm macro anymore. Everything compiles cleanly in gsll, but nothing has been tested.
