TOMS792
Tests for Interpolation of 2D Scattered Data


TOMS792 is a FORTRAN90 library which can be used to test the accuracy of programs that interpolate 2D scattered data, by Robert Renka.

TOMS792 is ACM TOMS Algorithm 792.

The original, true, correct version of this ACM TOMS algorithm is available in the TOMS subdirectory of the NETLIB web site.

Languages:

TOMS792 is available in a FORTRAN77 version and a FORTRAN90 version.
