public BicubicSplineInterpolatingFunction interpolate(double[] xval,
double[] yval,
double[][] fval)
throws NoDataException,
DimensionMismatchException,
NonMonotonicSequenceException,
NumberIsTooSmallException
- Compute an interpolating function for the dataset.
- Specified by:
interpolate
in interface BivariateGridInterpolator
- 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.fval
- The values of the interpolation points on all the grid knots:
fval[i][j] = f(xval[i], yval[j])
.
- Returns:
- a function which interpolates the dataset.
- Throws:
NoDataException
- if any of the arrays has zero length.
DimensionMismatchException
- if the array lengths are inconsistent.
NonMonotonicSequenceException
- if the array is not sorted.
NumberIsTooSmallException
- if the number of points is too small for
the order of the interpolation
