Method Detail

interpolate

CalculusFieldBivariateFunction<T> interpolate(T[] xval,
                                              T[] yval,
                                              T[][] 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.

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:

MathIllegalArgumentException - if any of the arrays has zero length.

MathIllegalArgumentException - if the array lengths are inconsistent.

MathIllegalArgumentException - if the array is not sorted.

MathIllegalArgumentException - if the number of points is too small for the order of the interpolation
