FINDSUBMAT find one matrix (a sub-matrix) inside another.
IDX = FINDSUBMAT(A,B) looks for and returns the linear index of the
location of matrix B within matrix A. The index IDX corresponds to the location of the first element of matrix B within matrix A. Only works for 2-d matrices or vectors, both of which may contain NaNs or Infs.

[R,C] = FINDSUBMAT(A,B) returns the row and column instead.

I would like to extend to N-D but don't have the time right now. This may be a future enhancement, but I believe the file stands on it's own just fine too.

Email me if bugs are found, thanks.
