Method Detail

interpolate

TrivariateFunction interpolate(double[] xval,
                               double[] yval,
                               double[] zval,
                               double[][][] fval)
                        throws MathIllegalArgumentException

Compute an interpolating function for the dataset.

Parameters:

xval - All the x-coordinates of the interpolation points, sorted in increasing order.

yval - All the y-coordinates of the interpolation points, sorted in increasing order.

zval - All the z-coordinates of the interpolation points, sorted in increasing order.

fval - the values of the interpolation points on all the grid knots: fval[i][j][k] = f(xval[i], yval[j], zval[k]).

Returns:

a function that interpolates the data set.

Throws:

MathIllegalArgumentException - if any of the arrays has zero length.

MathIllegalArgumentException - if the array lengths are inconsistent.

MathIllegalArgumentException - if arrays are not sorted

MathIllegalArgumentException - if the number of points is too small for the order of the interpolation
