      Comparison functions with more than two arguments · 5bfba33e
      Liam M. Healy authored
      The generic functions for comparison (<, >, etc.) have been renamed to
      have an "i" at the end, e.g. "<i".  A regular function has been
      defined for each that applies the generic function to each adjacent
      pair to determine the truth of the set.

      Relocation generic math functions and methods · 5fabe0c0
      Liam M. Healy authored
      The definition of generic math functions (addition, multiplication,
      etc.) has been moved from grid/generic.lisp to init/generic.lisp, and
      so is loaded before grid is loaded, with the methods that use grid
      functions moved to grid/functions.lisp.  This eliminates two warnings
      that were appearing in compilation.

      Add two arguments to atan · 485b39e6
      Liam M. Healy authored
      New arguments default and zero-enough to handle case where arctangent
      is undefined; if both numerator and denominator are essentially zero
      (that is, absolute value less than zero-enough), then return default.

      Grids cannot be scalars in operations with sequences · b47cb8b1
      Liam M. Healy authored
      When performing a mathematical operation with a sequence and a
      non-sequence, the sequence cannot be a grid.  Checking for this
      requires relocating generic.lisp with the generic mathematics
      definitions to a place in which it will be loaded after grid:gridp is

      Move funcall-dyadic · a038eb56
      Liam M. Healy authored
      Move #'funcall-dyadic to a new file physical-quantities/funcall.lisp
      so that it can use gird:grid and grid:gridp, which aren't defined
      where it is called, in generic.lisp.

      Dyadic functions with pq-grid arguments · 77e61dbe
      Liam M. Healy authored
      Fixed funcall-dyadic, which is used by basic arithmetic functions like
      #'*i, for cases where one or both arguments is a pq-grid.  In that
      case, the units are simply removed.  This is not as good as restoring
      the proper units after the calculation completes, but it is a step
      towards that goal.  New type 'grid:grid.

      Mathematical functions on grids · f022b844
      Liam M. Healy authored
      Define monadic and dyadic with scalar functions on grids.  In some
      cases, the same result is available for foreign-arrays using GSLL, but
      these definitions apply to all grids.  Improved formatting in "plain"
      style for 2D arrays; does not define ends of rows and columns but also
      does not inject TeXisms.

      Physical quantities with grids · 043a16fd
      Liam M. Healy authored
      Start implementation of physical quantities with grid magnitudes.
      Compiles and loads cleanly but mostly non-functional or only
      accidentally functional.

      Define math functions · 9324e05e
      Liam M. Healy authored
      Define generic simple math functions that have definitions for numbers
      in CL, like #'+, #'cos, etc.  These call the CL function if the
      argument(s) are numbers, but method(s) may be defined for non-numbers
      different objects.  Define a package antik-user which will import
      symbols from antik and other packages, but will be left to the user
      for other definitions.  Add copyright and license notice.
