|how to know whether a matrix is invertible|
I would like to know whether a matrix is invertible, I'm using ginv(), but if it's not, the library issues an error message and exits. I considered computing the determinant, but det() and det2() have the same problem. Is there a way to check this in PARI without an error and exit?
