Class Spline2DLeastSquaresEx1

java.lang.Object

com.imsl.test.example.math.Spline2DLeastSquaresEx1

public class Spline2DLeastSquaresEx1
extends Object

Computes a tensor-product cubic spline least squares fit to a function.

The data for this example comes from the function $e^x sin(x + y)$ on the rectangle $[0, 3] \times [0, 5]$. This function is first sampled on a $50 \times 25$ grid. Next, an attempt to recover it by using tensor-product cubic splines is performed. The values of the function $e^x sin(x + y)$ are printed on a $2 \times 2$ grid and compared with the values of the tensor-product spline least-squares fit.
