Thanks, I sort of tried that already by calculating the rank of the matrix through the Singular Value Decomposition method and then comparing it with the size of the matrix. As it turns out, the SVD algorithm is computationally much heavier than the LU algorithm. I wonder if there exist some...

Easy way of checking for matrix invertability? Hi everyone, I'm designing a particular algorithm and part of it requires to check if a given Matrix is invertible or not. Computation of the actual determinant is not necessary. So far I've been doing it with a LU factorization, and then...
