2004-03-25 Thread Jin Xuesong
I have 2D data of f(x,y) at irregular "grid" points and I wanted to do some interpolation so as to get this data on a regular(and denser) grid, so that I can further manipulate it with available packages. Is anyone aware of any package/software/code that can help me do this. (i.e. the mathematica a

2D interpolation from a randomly distributed 3D array

Hi, all I am facing a problem now and hope to get some help from you. The problem is: I collect a bunch of 3D data (x,y,z) which x and y are not uniformly distributed. To draw a contour graph, I need a matrix which is built from the (x,y,z) data. How can I do a 2D interpolation from a randoml
