      Relocate definition, optional arguments, nonlinear least squares streamline · 42cf5a7b
      Liam Healy authored
      Moved gsl-mfunction, def-mfunction, and gsl-mfunction-fdf from
      roots-multi.lisp to generic.lisp because they are common to several
      files in the solve-minimize-fit module.  Made arguments default
      instead of required in #'linear-mfit, linear-mfit-svd,
      weighted-linear-mfit, weighted-linear-mfit-svd.  Most of these do not
      have examples, so untested.  This required new functions
      #'default-covariance, #'default-lls-workspace.  Renamed examples to
      #'linear-least-squares-univariate-example and
      #'linear-least-squares-multivariate-example, and changed to
      'print-details.  Revised definitions in nonlinear least squares to
      streamline data flow; there is no setup function or global
      pre-declaration of the number of parameters or observations required
      anymore.  The example function now called
      nonlinear-least-squares-example will take the number of observations
      and the fitter method as optional arguments.

      Least squares added to tests, make arguments optional · f755beaf
      Liam Healy authored
      Coverted required args to optional args defmfun weighted-linear-mfit
      and replaced 'parameters with 'parameters-or-size.  Added print-steps
      options for several more examples, and put the newline at the end of
      the format string.  Added tests; CCL 64 bit now fails one of the
      linear least squares (returns zeros) and the nonlinear least squares
      (good to 6 or so significant figures).
      SBCL 64: TOTAL: 1231 assertions passed, 5 failed, 0 execution errors.
      CCL 64: TOTAL: 1234 assertions passed, 2 failed, 0 execution errors.

      Set mpointer vlaue, show relevant .h file; non-int return for reinitialize-instance · 8a0ac730
      Liam Healy authored
      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.

      Calling mobjects with #'mpointer, generic function #'name · 297c08b2
      Liam Healy authored
      GSL functions that take GSL objects as arguments must have #'mpointer
      called on each argument.  Created a generic function #'name and
      changed all the *-name (or name-*) functions that acted on mobjects to
      this function.

      Full use of defmobject; elimination of letm · b09dc9d2
      Liam Healy authored
      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.

      New class foreign-array, new names: marray, make-marray, mobject.lisp · 7c66d57b
      Liam Healy authored
      New class foreign-array represents foreign (C) arrays, without GSL or
      mobject superclass.  New class name 'marray was 'gsl-data,
      representing arrays in GSL.  These objects are made by #'make-marray,
      formerely #'make-array*.  New file names: init/mobject.lisp was
      init/gsl-objects.lisp and data/marray.lisp was data/data.lisp.

      Array input and output declarations · 1a2ebe96
      Liam Healy authored
      A somewhat comprhensive attempt to make sure :inputs, :outputs, and
      :return arguments in defmfuns match what the function is expecting and
      will return, so that non-native implementations will work correctly
      for copying, and native ones will work correctly for pinning.  The
      :return argument now defaults to :outputs in most circumstances.

      GSL array making with make-array* and #m · 83cd8040
      Liam Healy authored
      GSL arrays are garbage-collected objects, and so can be made like any
      other lisp object; they do not need to be make inside a wrapper form.
      #m is a macro which makes them; it expands to a #'make-array* call.
      Examples and usage ported to this new form.  Compiled only; not tested
      yet.  No effort to port to non-native implementation yet; tests as
      expanded in the tests/ directory are not ported yet.
