      Preliminary FFT functionality · 68d8dee7
      Sumant Oemrawsingh authored
      Only complex fast fourier transforms have been added. The radix-2 versions
      have been tested and found to work. The decimation-in-frequency versions have
      been added, but not tested. The mixed-radix versions only work for complex
      double-float at the moment.

      Fix defmfun expansion of default optional/key values · 5a5906dd
      Liam Healy authored
      For methods on marrays, all default values for optional and key
      arguments were wrongly coerced to the array element type.  This
      doesn't affect any current definitions in GSLL, but FFT functions with
      the stride specified, it will wrongly change the default value to the
      element type.  This has been fixed by changing #'actual-class-arglist
      so that it looks up the type intended to be passed to the C function
      and coerces to that if it is available.  Otherwise the expansion
      leaves the default value alone.

      Generalize set-matrix to have index limits · 33d52a9f
      Liam Healy authored
      Index limits may be passed to set-matrix and to some of the functions
      dependent on it, so that e.g. a tridiagonal matrix can be defined
      without iterating over all elements.  If the optional argument
      'pass-element is non-NIL, the function will be passed a final argument
      which is the prior value of the current element.

      QRPT: add tests, make arguments optional, fix bugs · a42b3a3a
      Liam Healy authored
      Added the translated GSL tests to the linear algebra for QR
      decomposition with column pivoting.  More arguments corresponding to
      values returned by the functions are now optional.  Fixed the order of
      return values from QRPT-decomposition so that permutation is before
      signum.  Fixed argument lists to QRPT-QRsolve.

      Cholesky: add tests; return argument for matrix-product · bcb8e0b5
      Liam Healy authored
      Added eight tests from GSL's test for Cholesky decomposition and
      solving.  The four decomposition tests incorrectly produce zero in
      CCL.  The first optional argument in matrix-product and
      matrix-product-symmetric can now be nil, to indicate a matrix of the
      right dimensions should be constructed.  This is the default; the
      default previously was to make that matrix directly, which meant if
      any other optional arguments were supplied, the complicated default
      construction for the return matrix would have to be re-entered.

      Test result is double-float · df63f1b6
      Liam Healy authored
      Add "d0" to test result for (test-qr-lssolve-dim *M53*) so that it's
      read as double-float; without that it is interpreted as single-float
      which gives a substantial discrepancy from the double-float result.

      QR: More optional arguments, add tests form GSL · 44b9d868
      Liam Healy authored
      Changed required to optional arguments for several of the QR linear
      algebra functions, for returned quantities.  45 new tests added for QR
      that are translated from GSL's tests.  Matrices and solutions that are
      used by more than one of the linear algebra techniques are defined in
      matrix-generation.lisp.

      LU linear algebra tests from GSL · 75f04669

      Added nine tests derived from the self-tests that GSL has for LU
      decomposition.  All tests except the complex matrix pass within the
      tolerances prescribed by GSL.

      Matrix generation for linear algebra tests · 72eaac6d
      Liam Healy authored
      Matrices (and vectors) may be created from functions of the element
      indices.  This is needed to create the matrices used in testing the
      linear algebra functions.  It also can be of general use, especially
      with further generalization.  For now, there are no exported symbols
      from these definitions.

      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
      :ri-c-return.

      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.

      Hand expansion of project-ntuple; start writing ntuple example · 9f1f9900
      Liam Healy authored
      In order to avoid or defer the complicated process of modifying
      defmfun definitions to handle two cbstructs, the definition of
      project-ntuple has been written by hand as a defun etc., by expanding
      a simpler defmfun and making the necessary modifications and mergers
      with an editor.  It has not yet been tested.  The test given in GSL
      ntuple/test.c is partially ported to Lisp.

      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.
