public TricubicInterpolatingFunction interpolate(double[] xval,
double[] yval,
double[] zval,
double[][][] fval)
throws NoDataException,
NumberIsTooSmallException,
DimensionMismatchException,
NonMonotonicSequenceException
Compute an interpolating function for the dataset.
- Specified by:
interpolate in interface TrivariateGridInterpolator
- 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.
NumberIsTooSmallException - if the number of points is too small for
the order of the interpolation
DimensionMismatchException - if the array lengths are inconsistent.
NonMonotonicSequenceException - if arrays are not sorted
