[petsc-users] Writing PETSc matrices

[Nunion]

What files should one use to convert vectors from Matlab to PETSc
(PetscBinaryWrite is for square matrices)?  I have attempted to write
directly to binary from Matlab a matrix + vector, and only a vector (using
save command with the -mat option), then read the binary file into PETSc
(using ex34.c in ...src/mat/tests), however the format is not recognized.

Thanks,

Tom
