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.
