• ### Method Detail

• #### interpolate

TrivariateFunction interpolate(double[] xval,
double[] yval,
double[] zval,
double[][][] fval)
throws NoDataException,
NumberIsTooSmallException,
DimensionMismatchException,
NonMonotonicSequenceException
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:
NoDataException - if any of the arrays has zero length.
DimensionMismatchException - if the array lengths are inconsistent.
NonMonotonicSequenceException - if arrays are not sorted
NumberIsTooSmallException - if the number of points is too small for the order of the interpolation
