interpolate
TrivariateFunction interpolate(double[] xval,
double[] yval,
double[] zval,
double[][][] fval)
throws NoDataException,
DimensionMismatchException
- 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.
