| This example of interpolation was done using the Modified Quadratic Shepard's method developed by R.J. Renka (see Multivariate interpolation of large sets of scattered data, R.J. Renka, ACM Trans. on Math. Software 14:2, June 1988, pp. 139-148.) The 5-variable function f(v,w,x,y,z) = [1.25+cos(5.4w)]*cos(6x)*cos(6y)*cos(6z)/ [6+6(3v-1)2] defined on all 100,000 nodes of a 10×10×10×10×10 grid was used to create the true results shown below. |
