Function sprs::io::read_matrix_market_from_bufread

pub fn read_matrix_market_from_bufread<N, I, R>(
    reader: &mut R
) -> Result<TriMatI<N, I>, IoError>where
    I: SpIndex,
    N: PrimitiveKind + Clone + Neg<Output = N> + MatrixMarketRead + MatrixMarketConjugate,
    R: BufRead + ?Sized,

Read a sparse matrix in the Matrix Market format from an io::BufRead and return a corresponding triplet matrix.

Presently, only general matrices are supported, but symmetric and hermitian matrices should be supported in the future.
