      Remove grid to the gsd/c-array repository · c75e91d2
      Liam Healy authored
      The grid subdirectory is now the c-array system within the GSD
      repository, as it has no GSL-dependent definitions and is potentially
      useful on its own for other C libraries.  There is a bare minimum
      mention of GSD in the documentation, which needs to be enhanced as it
      is required for GSLL to compile/load.

      Define foreign-array as subclass of grid:grid · 0c0834e1
      Liam Healy authored
      Define foreign-array as subclass of grid:grid with access to elements
      through grid:gref.

      Move copy-to-destination to grid · 06f99392
      Liam Healy authored
      The generic function definition for copy-to-destination is now in
      grid/ and the c-array package.  This will make it accessible to
      non-GSLL foreign library interfaces, but the new location is a bit
      deceptive because a new method needn't be a subclass of foreign-array.

      Moved some maref definitions to grid · f3a45c98
      Liam Healy authored
      Moved the defgeneric and methods for CL arrays and foreign-array for
      cl-array, maref and (setf maref) to a new file
      grid/element-reference.lisp.  The old file data/maref.lisp remains
      with the GSL pointer methods.

      Move foreign-array and foreign-friendly to grid · a9cf4a74
      Liam Healy authored
      Continuing the separation of definitions useful for any libraries
      using C arrays, foreign-array.lisp and foreign-friendly.lisp have been
      moved to the grid subdirectory and placed in the c-array package.
      All tests pass on SBCL 64,
      TOTAL: 1627 assertions passed, 6 failed, 0 execution errors.

      Continued separation of GSLL into two packages and eventually systems,
      the definitions in element-types.lisp are now in the c-array package.

      Split off grid directory · 8d5cd4a5
      Liam Healy authored
      Eventually, the definitions used for dealing with types and foreign
      arrays that aren't specific to GSL will be split off into another
      system, so that it will be easier to build other foreign library
      interfaces using these definitions.  As a start, the grid/ directory
      defines a package 'c-array and some of the type definitions formerly
      in init/.  Everything compiles and tests as before, on SBCL
      TOTAL: 1627 assertions passed, 6 failed, 0 execution errors.

      Added some extra functions for use with FFTs · 976eac7b
      Sumant Oemrawsingh authored
      fft-frequency-vector can be used to make a vector that contains the actual
      sample frequencies (so you don't have to guess or write your own).
      
      fft-shift and fft-inverse-shift shift the zero frequency to the center (for
      easy plotting), and the inverse (for proper inverse FFT).
      
      These functions are comparable to fftfreq, fftshift and ifftshift in numpy (if
      anyone cares...).

      Fast Fourier transform complete · ce3177ad
      Liam Healy authored
      The fast Fourier transform port now complete except for the tests.
      The backward, inverse, and selectable direction transforms are now
      unified in their respective files, a new file has been created for the
      wavetable and workspace mobjects.  The output of the example functions
      looks plausible.

      FFT Unpack · 7192e225
      Liam Healy authored
      Function #'unpack will switch between the various unpacking generic
      functions, depending on the specified unpack type and whether the
      vector length is a power of 2.  New file unpack.lisp has all the
      unpacking functions.

      Unify forward FFT into new file and function · b4f09c28
      Liam Healy authored
      The function #'forward-fourier-transform selects among the 12 GSL
      forward FFT functions, depending on whether the length of the vector
      is a power of 2, whether the :half-complex flag is set, and the type
      of the vector.  This exported function, along with its supporting
      internal functions, are in the file forward.lisp.  The dimension
      argument for fft-pulse-test is now mandatory.  All mobjects have been
      renamed so that they end with either -single-float or -double-float,
      consistent with the naming scheme in the rest of GSLL.  Eliminated
      (evidently) obsolete example file fft-example.lisp.

      Added attempt to clean FFT interface · dcc05d7f
      Sumant Oemrawsingh authored
      A hopefully nicer interface to the FFT functions are given, where the precise
      FFT function is deduced from the supplied vector. While the interface is
      nicer, the code is ugly, hacky and not fool proof yet. Cleanup required.

      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.

      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.
