how to make polar plot with N x M matrix

1 view (last 30 days)
I have a matrix N x M where the r cordinate length is N and the theta cordinate length is M.
I am trying to make surfac polar plot with colour bar but I dont want it to be 3d plot.
I am having hard time doing it.
thank for the helpers!
a=2/3; %ft
h = 1e-3; %step
r = [0:h:a]; % r axis
theta = [0:h:2*pi]; % theta axis
N = length(r);
M = length(theta);
% also I have T matrix N x M calculated

You can have a look at these file-exchange contributions: pcolor-in-polar-coordinates, perfect-polar-plots, 3d-polar-plot.
Or you could (first step perhaps) do it with surf/pcolor:
[r2d,theta2d] = meshgrid(r,theta);
shading flat % my personal preference
You might have to change order in and out of meshgrid or transpose YourMatrix.
