Detailed Description

"Raw" input of sparse matrices from Matrix Market files.

"Raw" means serial (not MPI or otherwise distributed over parallel processes), with storage as a collection of matrix indices and values. This is useful if you want to read the sparse matrix on one (MPI) process and store it in a custom format.

For reading a sparse matrix from a Matrix Market file into raw compressed sparse row (CSR) arrays on a single (MPI) process, use the Reader class. For reading in a Tpetra::CrsMatrix, use the Tpetra::MatrixMarket::Reader class. Nearly everything else in this namespace is of interest only to Trilinos developers.
