I want to convert from Cartesian to spherical coordinates in MATLAB. I have tried to use cart2sph in MATLAB but it is showing some error

You have to actually input the x, y and z vectors separately.Like [azimuth,elevation,r] = cart2sph(V(:,1),V(:,2),V(:,3));

Why not just do val(1,:,:) or val(i,:,:)?
