Dear group members, I am new to mathematica (well, I'm not actually but I haven't used it in 5 years +). Is there an easy way to return a matrix X of 1's and 0's to test whether the entries in Y are different from zero. i.e., if Y = {{a,b},{0,c}} Then X would return X = {{1,1},{0,1}} This would be handy for very large or complicated matrices where one would like to know if specific entries are zero? Many thanks, Paul
