I'm a fresher to MATLAB. i m looking for how to compare size of two images, if no then how to make the images to the same size.

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)])

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.
