How to determine if elements in a column are negative

I am developing a program for a class project to determine the states for a petri net. It will use the basic algorithm for a coverability tree. One of the first steps is determining the firability of a transition, and I would need to determine if any of the elements in a column of a matrix is negative. I looked through the function list and didn't see anything that would apply.
Any suggestions for either the column logic or petri net in general would be appreciated.
Thanks
