i have polar coordinates in a matrix 512x500 which can be displayed as in A with imagesc.
I can now convert them into cartesian coordinates. Since it is a spiral they will actually be cylindrical coordinates.
angle= linspace(0, 2*pi, size(polvec,2));
rad = linspace(1, 100, size(polvec,1));
[x,y,z] = pol2cart(a,b,c);
I also get a 2-D plot from above (B). But how do I convert this into a real 2-D transfomation? And how do I get a matrix out of it that now stores my data in 2D coordinates?
