interpolate
TrivariateFunction interpolate(double[] xval, double[] yval, double[] zval, double[][][] fval) throws NoDataException, NumberIsTooSmallException, DimensionMismatchException, NonMonotonicSequenceException 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.NonMonotonicSequenceException- if arrays are not sortedNumberIsTooSmallException- if the number of points is too small for the order of the interpolation
