size() applied to the variable will tell you the dimensions in each direction.

If you have the Image Processing toolbox then imresize() can resize images. For example,

newB = imresize(B, [size(A,1), size(A,2)])

[Image Analyst]

or simply newB = imresize(B, size(A)); if A is a monochrome image.

Not if A is an RGB image: size(A) would have 3 elements instead of 2 in that case.
