      Move copy-to-destination to grid · 06f99392
      Liam Healy authored
      The generic function definition for copy-to-destination is now in
      grid/ and the c-array package.  This will make it accessible to
      non-GSLL foreign library interfaces, but the new location is a bit
      deceptive because a new method needn't be a subclass of foreign-array.

      Use CFFI-grovel to define enumerations and programming constants · 5b255beb
      Liam Healy authored
      Instead of hardwiring GSL's #define or enum values, define them in
      init/libgsl-unix.lisp and run CFFI-grovel on them.  This has the
      advantage that if these values change in GSL, GSLL will automatically
      get the new values; also, there was an error in the 'integrate-method
      enum due to an incorrect starting value.  It has the disadvantage that
      building GSLL now requires a C compiler and some of the header (.h)
      files for GSL.  Also, it's not clear what the form for libgsl-*.lisp
      files are for non-unix OSes.

      Conditionalize FSBV · 8a08f552
      Liam Healy authored
      All source code is now conditionalized so that FSBV is optional.  If
      present, functions using complex scalars will work.  If absent, GSLL
      will compile and load correctly, and all functions except those using
      complex scalars will work.  The examples and tests are defined
      appropriately.  Documentation on FSBV dependence has been added to
      index.html.

      Redeclare foreign-allocated variables called by reference · 9848c6ad
      Liam Healy authored
      Variables called using with-foreign-objects that are passed to GSL for
      the purposes of returning computed values (i.e., are not mentioned in
      the CL arglist) need to be declared (:pointer type) because they are
      calls by reference.  Everything now compiles though there are
      execution errors in the tests.

      Use fsbv:defcstruct for complex, type spec (:pointer type) · 0b3847ba
      Liam Healy authored
      Define complex-float-c and complex-double-c using fsbv:defcstruct so
      that they can be passed by value.  A type specification of the form
      (:pointer type) is accepted for allocated objects passed by reference
      to foreign functions so that their values can be set and returned from
      the CL function.  This expands correctly for #'minmax, not tested
      yet.

      Add methods for #'elt- and #'elt/ that take scalars for the second
      argument.  Fix the docstring for (setf row) which had "column" instead
      of "row".  Export the symbols 'dim0 and 'dim1 because they are useful
      for users; use them in #'contents-from-pointer instead of previous
      dim1 and dim2 (et. sim. with size0, size1).

      GSL features added in version 1.9 · 6e17d879
      Liam Healy authored
      Added definitions for GSL features that were added in version 1.9, and
      one from version 1.10: mminusp, mplusp, non-negative-p,
      +knuthran2002+, +vector-bfgs2+.  Macros defmpar now has key instead of
      optional args.  It and def-rng-type take a gsl-version argument; any
      symbols that are not defined in the user's version of GSL will be
      bound to an instance of 'obsolete-gsl-version but it is not signalled.

      Copy to and from CL arrays · 6a685571
      Liam Healy authored
      The function #'copy will now copy contents between marrays and CL
      arrays.  The destination array can be supplied literally, or created
      by this function by specifying the desired type: when copying from a
      marray to a CL array, specify 'array; when copying from a CL array to
      a marray, specify the element type of the marray.  For example,
      (COPY
         (COPY
          (MAKE-MARRAY '(COMPLEX DOUBLE-FLOAT) :INITIAL-CONTENTS
                       '((-34.5 8.24 3.29 -8.93 34.12 -6.15)
                         (-8.93 34.12 -6.15 49.27 -13.49 32.5)
                         (49.27 -13.49 32.5 42.73 -17.24 43.31)))
          'ARRAY)
         '(COMPLEX DOUBLE-FLOAT))
      copies from the matrix-complex-double-float made in the make-marray
      form to a CL array, then copies the contents to a new
      matrix-complex-double-float.

      Redefine #'copy · 419e70d4
      Liam Healy authored
      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.

      Elementwise array operations named "elt" · 4bfa337d
      Liam Healy authored
      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.

      Generic functions for array addition, multiplication with scalar · 2747131e
      Liam Healy authored
      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.
      CCL: TOTAL: 1228 assertions passed, 0 failed, 0 execution errors.

      Use class foreign-array · 74d8995a
      Liam Healy authored
      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.

      Complete set of tests on array operations that are defined for both

      #'expand-defmfun-generic that occured when both arrays are generated,
      due to key-args being altered.

      #'array-default makes both vectors and matrices; pool numbers with correct type · f8adee82
      Liam Healy authored
      For testing, both vectors and matrices can be made with
      #'array-default, replacing #'vector-default.  The numbers in
      *double-float-pool* in are now double floats (with d0), and the
      #'make-list-from-pool coerces to the right type.  In both.lisp,
      #'set-value and #'get-value are for vectors only, not both, because
      matrices require an extra index argument.  Since these functions are
      for debugging only as the comment says, I'm writing equivalent matrix
      functions, and I'm not doing tests for them.

      New function #'complete-definition is for putting together an entire
      definition with arglist, declaration, and body, such as defun,
      defmethod, or :method.  The old (misleadingly-named)
      #'expand-defmfun-plain has been removed.  Removed possibility of
      definition &aux variables with :global; it was used only once and
      easily replaced.
