Convert data plot from Cartesian to spherical coordinates

6 views (last 30 days)
I have data plot shown below where the 'x' and 'y' coordiantes corresponds to the cartessian coordinates sin(theta) cos(phi) and sin(theta) sin(phi). I would like to obtain a plot where the 'x' and 'y' coordinates are theta and phi. Is there a command in Matlab that performs this coordinate transformation? theta and phi are the spherical coordinates.

See if the cart2sph function will do what you want.

I tried cart2sph the image obtained is not right. In the initial data theta varies form -pi/2 to pi/2 and phi varies from 0 to 2*pi

It may be necessary to plot it with the surf function to see it correctly.
Beyond that, I have no idea what the problem could be.
