Can't really relate to the last comment. My interest in MatrixMarket format is not to shoot myself in the foot. Rather, it is because of 2 different reasons. One is that 2 different vendors have asked for some sample matrices from the problems I solve and their format preference is MatrixMarket.

The amount of code to write a MatrixMarket file is less than the length of this email.

Second is that I would like to test some of my matrices with the new version of cholmod that has gpu support since I have seen good performance with other matrices and I have not been able to get cholmod to work with cublas in petsc yet. Petsc crashes when I try to call cholmod with its cublas support.

I think time is better spent debugging that problem.

However, cholmod has a test program that can read and solve systems which are input via MatrixMarket format. I certainly don't want to shoot myself in the foot or use MatrixMarket format for any sort of production scenario.

Thanks for the suggestions. I'll look into exploring python for this task.
