Module mtx 

Matrix Market I/O.

sprs::io::write_matrix_market_sym writes the upper triangle, but the Matrix Market spec calls for the lower triangle (i ≥ j). To stay compatible with strict readers (e.g. fast_matrix_market), we hand roll the symmetric writer. We delegate to sprs for general (non symmetric) output and for reading.

Functions

read_mtx

Read a Matrix Market file into a CSR matrix.

read_vector_mtx

Read a dense vector written by write_vector_mtx (array real general): %-comment lines, a <len> 1 dimensions line, then one value per line.

write_mtx

write_vector_mtx

Write a dense vector as Matrix Market array real general.
