So I decided to just make a contains function but I wanted to make it work for lists,vectors and matrices but I couldn't find any way to flatten a matrix or turn it into a list.

Any suggestions?

mat2list([[1,2],[3,4]]) --> {1,2,3,4}.
Therefore, ΠLIST(mat2list(matrix)) returns 0 if any matrix elements are zero.
