interpolate
TrivariateFunction interpolate(double[] xval, double[] yval, double[] zval, double[][][] fval) throws MathIllegalArgumentException 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:
MathIllegalArgumentException
- if any of the arrays has zero length.MathIllegalArgumentException
- if the array lengths are inconsistent.MathIllegalArgumentException
- if arrays are not sortedMathIllegalArgumentException
- if the number of points is too small for the order of the interpolation
