Module Modifed Quadratic Shepard
Modified Quadratic Shepard method for grid interpolation from irregular distributed points. This module is based on Module 660 in TOMS.
QSHEP2D: Fortran routines implementing the Quadratic Shepard method for bivariate interpolation of scattered data (see R. J. Renka, ACM TOMS 14 (1988) pp.149-150).
Classes: E2b. Interpolation of scattered, non-gridded multivariate data.
