Victor and Richard, The files mm2petsc.c, mmio.c and mmio.h are attached. I just update it with petsc-dev (petsc-2.2.1 should be fine). Let me know if you see problem/bug. If you further improve it, please give me your improvement as well. Thanks, Hong On Tue, 5 Apr 2005, Victor Eijkhout wrote:

We have code that read MatrixMarket format, and write into a petsc binary file. Then you can use petsc MatLoad() for viewing or computation.

I'm interested in this too. I wrote my own version. Maybe a good idea to add this to the petsc distribution? -- Victor Eijkhout <[email protected]>, 329 Claxton, Comp Sci, UT, Knoxville TN 37996. tel: 865 974 9308 (W), 865 673 6998 (H), 865 974 8296 (F) http://www.cs.utk.edu/~eijkhout/
