- HELP!! For a project I'm doing for work I require a routine to take the
- Inverse of a very large matrix (in the order of 1000x1000). The
- Matrix Inverse function tends to bomb out at even a 10x10 matrix.
-
- I am assuming that some sort of Gaussian Elimination routine is
- needed. Is there somewhere where I could find a pre-written routine?
-
- I realize that for a matrix so large, it would probably take a LONG
- time to run. But could anyone guestimate what kind of time I'm
- looking at? Minutes? Hours? If it means anything, most of the
- entries in the matrix will be zero.
-
-
- Any help would be appreciated!
-
- Brad.
