Eda,
An update to ex72 is merged to PETSc master branch just now. It now can read
matrices either symmetric or non-symmetric in Matrix Market format, and output
a petsc binary matrix in MATSBAIJ format (for symmetric) or MATAIJ format (for
non-symmetric). See help in source code for usage.
Don't know why it should cause problems. I'd rather try before asking.

Dear Professor Roman,
Thank you for your answer. I used PetscBinaryWrite.m file and converted
matrices into binary format but I have a question:
When I look at Properties of the binary files Petsc have, their type is
stated as "Program (application/octet-stream)", however when I checked the
We should make the (two line) functionality a command-line feature of
PetscBinaryIO.py. Then a user could do
python -m PetscBinaryIO matrix.mm matrix.petsc

Hi Junchao,
Could you fix the MM example in PETSc to have this full support? That way we
will always have it.
Thanks,

Eda,
I have a code that can read in Matrix Market and write out PETSc binary
files. Usage: mpirun -n 1 ./mm2petsc -fin -fout . You can
have a try.

It is better to convert the matrices to PETSc binary format first. One easy way
is to read them into Matlab with mmread.m and write with PETSc's
PetscBinaryWrite.m. This can be done similarly in python.

Hello,
I am trying to load matrix in Matrix Market format. I found an example on
mat file (ex78) whih can be tested by using .dat file. Since .dat file and
.mtx file are similar in structure (specially afiro_A.dat file is similar
to amesos2_test_mat0.mtx since they both have 3 columns and the
