i am not knowing what to do.how to make the z and w the different sizw..?

[Walter Roberson]

Your z and w are currently different sizes. As you appear to be using images, you should imresize() the larger image to match the size of the smaller image.

[Walter Roberson]

We have no reason to expect, given the code you show, that z and w were originally the same size. If they are not, then it will not be possible to multiply their binary equivalents.
