NAME¶

dsgrid - grid 2D and 3D randomly-spaced data

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):
--------------------------------------------------
