Hi Everyone

I think I'm being dumb but I have a set of 2d data (2d array) z

(100x100) which I need to plot - I have a nominal set of x and y

positions say:

x = linspace(0,100)

y = linspace(0,100)

Now the actual positions of the points in z are given by the following:

u,v = meshgrid(x,y)

phi = arctan2(v,u)

theta = arcsin(u/cos(phi))

so I have three 2d arrays (100x100) which describe the postion

(phi,theta) of the points in z

How do I go about plotting these say using imshow?

Cheers

Ross
