Hi,

I have two 3D matrices of ones (and zeros) of a (filled) cone like shape. The matrices are the same size, but the cone sizes differ. I want to "subtract" the smaller of the two matrices from the other matrix element by element. resulting in a third matrix of the "leftover" ones (and zeros). A-B = C doesn't seem to work. Does anybody have an idea on how two do that?

Two matrices should be same to subtract. Get them to same size. As your matrices are filled with 0 and 1.

Hi KSSV,

Thanks for your answer. The sizes were the same. But I found a mistake in the buildup of the cones. Thank you anyway! Do you happen to know how to 3D plot a matrix of ones determined by their position in the matrix?

Kind regards,

David
