      Simulated annealing loaded in defsystem · 5e1b9c33
      Liam Healy authored
      Simulated annealing is now loaded with the defsystem, and its presence
      advertised in documentation/index.html.  The file
      simulated-annealing.lisp has been moved to solve-minimize-fit.
      The GSL "make check" tests have been added at the end of the file, but
      they are not added to GSLL's examples/tests yet because of how slow it
      runs.

      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.

      Eliminated dependency on cl-utilities; error for obsolete defmpar · 45ca8e88
      Liam Healy authored
      The defmobject argument 'class-slots-instance is no longer used, so
      #'callback-arg-p and the only use of with-unique-names can be
      eliminated, and thus the dependency on cl-utilities.
      
      Constant GSL functions in the library (such as minimizers) which
      were introduced in a GSL version newer than loaded now expand as
      symbol macros which signal the 'obsolete-gsl-version error.

      Pure defmfun callbacks dynamically specified fully functional · 42e2d608

      Redefine the form of :callback-dynamic to be

      hardwired.  If manually defined (defconstant +success+ 0),

      Extend #'copy to copy to or from mpointers · efa2315f
      Liam Healy authored
      Both copy-to-array and copy-making-destination have been extended so
      that an mpointer can occur as the first or second argument.  If the
      first argument, the second argument should be a symbol representing a
      subclass of marray.  If the second argument is not present
      (copy-making-destination), 'vector-double-float is assumed.  If the
      mpointer is the second argument, the marray contents are copied into
      its contents.  These methods are useful for callbacks and GSL
      functions that send raw mpointers.  For example, a callback that uses
      foreign arrays directly can simply copy from and to them.  This has
      been applied in the solve-minimize-fit functions that return a raw
      mpointer, replacing the explicit call to make-marray.  The first
      argument to #'marray can now be either the class name or element-type.

      Order of arguments in linear-mfit, export symbols, documentation update · 352210f5
      Liam Healy authored
      Swapped the optional arguments 'weight, 'tolerance to linear-mfit on
      the assumption that weighted fits are used more often than SVD.
      Exported symbols for the generic functions defined in generic.lisp
      (note: this will require shadowing when importing both the :gsl
      package and the :iterate package).  Various minor improvements/updates
      to documentation.

      Monte Carlo uses direct function callbacks · bcf61476
      Liam Healy authored
      Direct function callbacks may now be used with GSL structs other than
      'gsl-function, and will set the 'dimension slot as well by looking at
      the arglist of the function sent.  This uses an #'arglist borrowed
      from CLOCC:port.  Rewrite make-callbacks based on a hash table rather
      than a generic function.  All the usualy tests pass.
      SBCL 64:
      TOTAL: 1259 assertions passed, 5 failed, 0 execution errors.
      CCL 64:

      Use lambda forms in callbacks · b134ed94
      Liam Healy authored
      It is possible to use lambda forms as well as function names in
      callback definers; this is demonstrated in the Monte Carlo example.
      Eliminated make-mfunction and folded its functionality into
      make-solver-functions.  Added a section to the documentation to
      explain how function definitions work.

      Define callbacks by returning the struct pointer, without setting specials · f0c7ecec
      Liam Healy authored
      Macro defcbstruct and all the macros built on it now simply return the
      C struct needed by GSL functions instead of binding a special whose
      name is then passed to the GSL functions.  Specials can still be used
      of course in the standard way like defparameter, but the results can
      also be bound locally with a let or passed in directly.  The name of a
      callback passed to defmcallback and to defcbstruct in all the macros
      that expand both is now gensymmed (since it is used only long enough
      to put in a slot of the cbstruct) instead of taken to be the name of
      the CL function, in order to make clear the different objects.
      Unfortunately, there is appears to be a bug in CFFI using defcallback
      with an uninterned symbol in CCL, so I have put a workaround in.
      However, there is still another error even with this workaround.
      Thus test results are:
      SBCL 64: TOTAL: 1248 assertions passed, 5 failed, 0 execution errors.
      CCL 64: TOTAL: 1229 assertions passed, 2 failed, 6 execution errors.

      Remove cl-utilities dependence · 1b22bb29
      Liam Healy authored
      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.

      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.

      that is a summary of test pass/fail on various implementations and
      platforms, and missing-features.text that documents features of GSL
      that aren't included.

      Started in file init/analysis.lisp some definitions that will aid in
      gauging how much of GSL GSLL covers.  It will not normally be loaded
      (and depends on port system which is not required for GSLL) because it
      is mainly used by developers.  It is not yet finished.  Hash size for
      *gsl-symbol-equivalence* increased to reflect actual number of symbols
      present when GSLL is loaded.  Improved documentation.
