public BicubicSplineInterpolatingFunction interpolate(double[] xval,
double[] yval,
double[][] fval)
throws MathException,
IllegalArgumentException
- Computes an interpolating function for the data set.
- Specified by:
interpolate
in interface BivariateRealGridInterpolator
- 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 data set.
- Throws:
MathException
- if arguments violate assumptions made by the
interpolation algorithm.
