- 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.
