INTERP3: A computer routine for linear interpolation of trivariate functions defined by nondistinct unequally spaced variables

摘要

A report on the computer routine INTERP3 is presented. The routine is designed to linearly interpolate a variable which is a function of three independent variables. The variables within the parameter arrays do not have to be distinct, or equally spaced, and the array variables can be in increasing or decreasing order.
