I am interesting in sparse matrix that defined at here. I am looking for a fast algorithm to invert the matrix (better than Gaussian Elimimation). Could you suggest to me some methods that reduce computational time? Note that the matrix is sparse and large. For example $100 \times 100$ or $500\times500$. Thanks
