[Trilinos-Users] Matrix file format

I have my sparse matrix in (row)(column)(value) format, which fortunately
seems to be the same as matlab format.

I hence tried to use EpetraExt::MatlabFileToCrsMatrix, this way:

Epetra_SerialComm Comm;
int MyPID = Comm.MyPID();

char FileName[] = "matrix_100.dat";
Epetra_CrsMatrix * F;

int EpetraExt::MatlabFileToCrsMatrix ( FileName,Comm,F);

Though, I get the following error:
error: invalid use of qualified-name ‘EpetraExt::MatlabFileToCrsMatrix’

Any idea?

Thanks in advance!
