# Trigonometric Interpolation: 2-dimension

2018-03-12 20:21:08

2 dimensional interpolation over the region

[-$\pi$/2,3$\pi$/2]$\times$[-$\pi$/2,3$\pi$/2]

The nodes that we know are given as follows:

Points Values

(0,0) -0.3574

(pi,0) -0.3294

(0,pi) -0.3294

(pi,pi) -0.2967

Calculate the trignometric interpolation with partition stepsize pi/4

I am having trouble understanding the 2-dimensional interpolation, any help would be appreciated.
