I thought it can be done without using a loop. Maybe I could not understand your question properly because you did not elaborate it well enough.
Here is a code explaining what I did
x = random('gaussian',0,1,[1,50]); %Generating one set of random numbers
y = random('gaussian',0,1,[1,50]); % Generating other set of random numbers
[t,r] = cart2pol(x,y); % Convert from cartesian to polar form
% t will contain the theta part , and r will contain the rho part
If you dont think it is what you want to do , then reply back with a clearer version of the problem
