      List argument to defmobject :initialize-suffix · 8555fb6a
      Liam Healy authored
      A list argument to defmobject :initialize-suffix now means what a list
      argument to defmfun to defmfun c-arguments does: there are two foreign
      functions corresponding to the Lisp function; in this case, to
      reinitialize-instance.  The old meaning of having the second element
      specify the c-return reinitialize-instance has been eliminated;
      instead, this information is conveyed in a new key argument

      Multiple foreign functions in the reinitialize-instance for mobjects · 9990ee06
      Liam Healy authored
      It is now possible to specify two foreign functions for the
      reinitialize-instance for defmobject.  The switch between the function
      depends on the presence or absence of optional/key arguments.  This is
      used in the definition of one-dimensional-minimizer to switch between
      gsl_min_fminimizer_set and gsl_min_fminimizer_set_with_values
      depending on the non-NIL value of f-minimum.  The set-with-values case
      has not yet been tested.

      Handle cflags in the grovel file · 6f287646

      Handle conditional cflags in the grovel file instead of modifying the
      cffi-grovel::*cc-flags* variable.  Also use strings for depends-on
      in asdf file.

      Fix multidimensional minimization with scalarsp · a2ba427b
      Liam Healy authored
      In the definition of multi-dimensional-minimizer-fdf, the dimensions
      of the :output for df and fdf have been corrected by removing an extra
      dim0.  The parabaloid example has been implemented using scalars, and
      the results match that of the vector form.  A test has been added for
      the scalar form.

      Grovel physical constants using new CFFI-grovel · 5386a514
      Liam Healy authored
      Stelian Ionescu has modified CFFI-grovel to generate double-float
      constants with :type double-float in constant.  GSLL has been ported
      to use that.  This requires a version of CFFI which includes the patch
      of Mon Jun 8 10:29:44 EDT 2009.  It works, but until this has a
      release number, it will stay out of the master GSLL branch.

      Define C structures using CFFI-grovel · 8c0e6eb7
      Liam Healy authored
      Almost all GSL structures are now defined using CFFI-grovel, which
      makes the code more robust should there be changes in GSL.  The
      exceptions are complex-float-c, complex-double-c, and
      simulated-annealing-parameters; because these structures are used by
      value, they need to be defined with fsbv:defcstruct at the present.

      Physical constants added · 722fa9e2
      Liam Healy authored
      All physical constants in gsl/gsl_const_mksa.h and
      gsl/gsl_const_cgsm.h are defined as Lisp constants and exported.  This
      requires a patch to CFFI grovel/grovel.lisp.  Since this patch has
      just been sent to the CFFI mailing list and is not generally
      available, this will remain off the master branch until the patched
      CFFI is generally available.

      Use CFFI-grovel to parse physical constants · a683fea3
      Liam Healy authored
      Started writing definitions of constants based on GSL's physical
      constants, using cffi-grovel.  This has not proceeded beyond the first
      definition because cffi-grovel at the present time casts everything to
      an integer.

      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.

      Simulated annealing is now loaded with the defsystem, and its presence

      Simulated annealing functioning · 1bc6155e
      Liam Healy authored
      Simulated annealing now works.  The trivial example given in GSL
      source doc/examples/siman.c is coded up at the end of
      simulated-annealing.lisp.  Both versions produce the same
      #<VECTOR-DOUBLE-FLOAT #(1.3631300129927695d0)>
      Note that the parameters for this example are slightly different than
      what is given in the manual; the manual version of the parameters are
      commented out in #'simulated-annealing-example.
      The Lisp version takes about 26.5 seconds, the C version about 0.85
