I am interested in C code for the manipulation of a VERY large matrix. Basically, what I need to do is perform an LU decomposition on a matrix too large to operate on the whole thing at once. Therefore, I need an algorithm that allows me to operate on chunks of the matrix at a time, and which allows an in-place LU decomposition, so that I can minimize the amount of disk storage necessary for the computations. Any help is GREATLY appreciated. -- Henry J. Cobb hcobb@fly2.berkeley.edu SFB Tyrant "Once it becomes possible to do something, it gets very difficult to undo it. Whether its automobiles, computers or nuclear weapons, invention has always been the mother of necessity."
