From: "F. Grund, WIAS Berlin"
I put the files
bayer.tar.gz
chem.tar.gz
poli.tar.gz
in your subdirectory pub/faculty/davis/incoming
The matrices in bayer.tar.gz are of the german chemical industry
(chemical process simulation).
In chem.tar.gz you find matrices of demonstration examples of the
chemical process simulator SPEEDUP.
The two matrices in poli.tar.gz are of account of capital links. The
problem is:
Determine the inverse matrix of I-A. I is the unity matrix and A a matrix
with elements a(i,j) and
0 <= a(i,j) < 1
The elements b(i,j) of B = (I-A)**(-1) are >= 0. These matrices are
very sparse and the fill in is very small.
Best Regards,
