How to turn a matrix and convolve it?

I would like turn a matrix and convolve it with an other one. I have tried this kind of solution, but it doesn't work finally:
dx=1:size; dy=1:size; [x,y] = meshdom (dx,dy);
%Transform Cartesian coordinates to polar [t,r,z]=cart2pol(x,y,matrix_A); %Turn matrix_A by 0.5 rad t=t+0.5;
%Transform polar coordinates back to Cartesian [X,Y,Z]=pol2cart (t,r,z);
%What should I do to make this possible with the new matrix_A: matrix_B = any_matrix; filter2 (matrix_A, matrix_B, 'valid');
Thanks for any kind of help!
