HII am trying to convert a sparse matrix from matlab data file to PETSC binary file. While PETSC offer an example  (\src\mat\examples\tests\ex72.c) to convert Matmarket file to binary. It is too slow for me. My matrix is 1.7 M * 1.7 M with 62 M non zeros. So, is there any faster way to convert it? Or is it possible to write to it one line by one line ?Thank you
