Finding a sub-matrix in a bigger matrix

the input data are row and column of a main and a sub matrix. then the program has to say "yes" if the sub-matrix is found in the main one. I have no idea about the algorithm. I mean, the method to find a sub-matrix in a bigger matrix. I'm really confused by that.

plz help. tnx.

Hmm... are you familiar with the various algorithms for finding a substring within a string? You could draw some inspiration from well known solutions to that problem (and after all, a string can be seen to be a row (or column) vector of characters).
