RANDOM  INTERPOLATION
Lower Dimensionality
(More Sample Case, 2D)

The sample function has the analytic form:

where   -10. < x1 < +10. and   -10. < x2 < +10.

For this sample case, we have used 12 random locations together with the associated function values to construct the interpolant. Also, delta width values of X1 and X2 are chosen to be 1.

INTERPOLATION RESULT

Provide the desired location ( x1, x2) where the interpolated function value fINT( x1, x2) is calculated.

x1:     ( -10. < x1 < +10. )

x2:    ( -10. < x2 < +10. )

Click "COMPUTE" button to find fINT(x1, x2) and f(x1, x2):

         fINT(x1, x2):

     The true value of  f(x1, x2) is :
