public TricubicSplineInterpolatingFunction interpolate(double[] xval,
double[] yval,
double[] zval,
double[][][] fval)
throws NoDataException,
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.
DimensionMismatchException - if the array lengths are inconsistent.
NonMonotonicSequenceException
