[Trilinos-Users] How to read a MatrixMarket File

[Heroux, Michael A]

Hi Virginia,

To the best of my knowledge there is no supported functionality for this.  There is some chance that another user has done something.  I seem to recall that a student of Jonathan Hu did something like this.  Jonathan?

Hi, everybody.
Does anybody know how to read a MatrixMarket file to a BlockMap?
I tried to do this:

int main(int argc, char *argv[])
{
    Epetra_SerialComm Comm;
    Epetra_BlockMap *BMap;
    EpetraExt::MatrixMarketFileToBlockMap("bcsstk14.mtx", Comm, BMap);
    Epetra_VbrMatrix A(Copy,*BMap,2);
    cout<<A;
}

But it's returns a segmentation fault.

thanks.

Virginia.
