Question

I would like to create an annular plot of a function z=f(x,y), such as

in MATLAB. My data (x,y,z=f(x,y)) is in a csv file, which I can read in MATLAB. The problem is that x and y are not given as a regular grid, ie, they do not resemble the output of the meshgrid command. Any suggestions?

Answer 1

So you're problem is that the data is scattered and not on a regular grid?

try doc griddata
