      New function #'cl-cffi renamed from #'cl-ffa · d9e5bb32
      Liam Healy authored
      To make terminology consistent, the "C standard" form of type, also
      what I call "CFFI" form, is called that instead of "FFA" in some
      places.  Specifically, #'cl-cffi is renamed from #'cl-ffa and now the
      name matches the already-existing #'cffi-cl.

      Mean and variance for all arrays · 370307e4
      Liam Healy authored
      Define mean and variance functions for matrices as well as vectors.
      This required a modification to #'expand-defmfun-generic and to
      #'actual-array-c-type to permit the use of "both" when there is an
      optional argument, and thus two C argument lists.  Defined tests for
      all unweighted functions and element types.  Because there appears to
      be a bug in the GSL library in computing single floats, no tests have
      yet been defined for these functions.

      Complete "both" array tests · 32b971a4
      Liam Healy authored
      Complete set of tests on array operations that are defined for both
      vectors and matrices.  Added documentation to generate-tests to
      explain how it works and why it's there.  Fixed bug in
      #'expand-defmfun-generic that occured when both arrays are generated,
      due to key-args being altered.

      Fix definition of #'euclidean-norm and defmfun :component-float-type · c6fa7363
      Liam Healy authored
      The function #'euclidean-norm (gsl_blas_*_nrm2) takes one vector
      argument, not two, and returns the result as a return from the
      function.  Handling of return declaration :component-float-type for a
      method created with defmfun was wrong, because #'component-type alread
      returns the C type and does not need to be converted with #'cl-ffa.

      Clean up several compilation problems · 134132bc
      Liam Healy authored
      Several bugs with small fixes, modifications to eliminate warnings:
      - Bad names for argument variables in maref fixed.
      - Add depenedencies in gsll.asd to avoid warnings.
      - Histogram needs #'assign-pointer function which was previously
      - #'scale is a generic function, change defun to defmethod in
      - New #'variables-used-in-c-arguments replaces #'c-arguments in
        defmfun, now is a simplistic code walker but goes to arbitrary
        depth.  This will do for current uses of defmfun.
      - Export and defgenerics for #'alloc, #'free which are used by
        histogram and random.  In gsl-objects.lisp for lack of a better
      System now completely compiles from scratch with only one warning 
      "Implicitly creating new generic function BIND-GENERATE-BINDINGS."
      which is from metabang-bind.  No new testing.

      Maref and (setf maref) for GSL vector pointers; optional arguments in :method · 3cf4781e
      Liam Healy authored
      The generic function #'maref will work on foreign pointers and assume
      them to be pointing to either a gsl-vector-c or a gsl-matrix-c,
      depending on how many indices are given.  This then functions like the
      old #'vref and #'mref.  It is used in the new function
      #'make-vector-from-gsl which creates a CL vector (using make-array*)
      which is needed by several functions in solve-minimize-fit.  It is
      also useful in the callbacks a user would define for
      solve-minimize-fit functions.  Similar functionality added to (setf
      aref) which was turned into a generic function.
      As part of the changes needed to define these methods, the defmfun
      family was modified to accept optional arguments in
      #'expand-defmfun-method, which is invoked when :definition :method is
      given.  Functions with optional arguments fall into two categories as
      far as defmfun is concerned: those that correspond to multiple GSL
      functions, and those that don't.  This should work in both cases.

      Introduce #'body-optional-arg and #'body-no-optional-arg · cd52a733
      Liam Healy authored
      Introduce #'body-optional-arg and #'body-no-optional-arg (formerly
      functions and the second specifies whether to map down on the C
      argument list on order to find all variables that are used.  All of
      GSLL compiles.

      New function #'complete-definition · dfda5c5b
      Liam Healy authored
      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.

      New function #'expand-defmfun-body · 296feb06
      Liam Healy authored
      Extract new function #'expand-defmfun-body from
      #'expand-defmfun-plain, then define the latter in terms of the former,
      with the idea that it will be easier to define other forms (defmethod,
      :method by calling this new function separately.  GSLL compiles with
      the new function.

      Tri- and bi-diagonal linear systems ported to ffa · 383cfb06
      Liam Healy authored
      Uses generic functions to cover both symmetric and hermitian solutions
      for the tridiagonal functions that have both.  This necessitated
      modifying #'actual-gsl-function-name to allow explicit listing of the
      GSL functions by element type.

      Explicit precision specification modes · 6f90daf7
      Liam Healy authored
      The GSL precision mode used mainly in special functions is now
      explicitly given in the CL argument list; remove special treatment of
      :mode in C argument list of defmfun call, which meddled with the CL
      arglist.  Changed sf-mode options to :double, :single, :approx.

      BLAS1 function #'scale with real or complex scalar · d5c1871f
      Liam Healy authored
      There are two BLAS1 functions "gsl_blas_csscal" and "gsl_blas_zdscal"
      that scale complex vectors with a real scalar alpha.  In order to
      distinguish a call to #'scale between these and the equivalent
      functions gsl_blas_cscal and gsl_blas_zscal that take complex scalars,
      it is necessary to specialize on the scalar class (float or complex).
      Modified defmfun so that the pseudo-classes :component-float-type and
      :element-c-type are recognized and the appropriate substitution is
      made.  Compiled without errors or warnings but not tested.
