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.
