How to multiply 3d-arrays without image processing toolbox

Don't resize the Image, resize the Mask. I am assuming the Mask is 0/1 binary, so use nearest neighbor interpolation method.

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));
