Dsgrid(3NCARG)

NAME
Dsgrid is a package for gridding 3D and 2D randomly-spaced data using an inverse distance weighted average algorithm. Single precision and double precision interfaces exist in both Fortran and C.

SYNOPSIS

FORTRAN single precision
------------------------

 DSGRID2S - primary function for gridding 2D data.
 DSGRID3S - primary function for gridding 3D data.
 DSSETI - set INTEGER parameter values.
 DSGETI - retrieve values for INTEGER parameters.
 DSSETR - set REAL parameter values.
 DSGETR - retrieve values for REAL parameters.
 DSSETC - set CHARACTER valued parameters.
 DSGETC - retrieve values for CHARACTER parameters.
 DSPNT2S - interpolate 2D data at specified points.
 DSPNT3S - interpolate 3D data at specified points.

Fortran double precision (not supported on UNICOS):
--------------------------------------------------

 DSGRID2D - primary function for gridding 2D data.
