public class TrilinearInterpolator3
extends java.lang.Object
The function y(x1,x2,x3) is specified by samples on a regular grid, which need not be uniform. The regular grid is specified by one-dimensional arrays of monotonically increasing coordinates x1, x2 and x3, such that gridded x1 are identical for all gridded x2 and x3, gridded x2 are identical for all gridded x1 and x2, and gridded x3 are identical for all gridded x1 and x2.
Extrapolation (that is, interpolation outside the specified grid of (x1,x2,x3) coordinates), is performed using linear polynomials for the nearest grid samples. Extrapolated values can be well outside the [min,max] range of interpolated values, and should typically be avoided.
