Function nalgebra_sparse::io::load_coo_from_matrix_market_file

pub fn load_coo_from_matrix_market_file<T, P: AsRef<Path>>(
    path: P
) -> Result<CooMatrix<T>, MatrixMarketError>where
    T: MatrixMarketScalar,

Parses a Matrix Market file at the given path as a CooMatrix.

The matrix market format specification does not clarify whether duplicate entries are allowed. Our importer assumes that this is permitted and produces a CooMatrix with possibly duplicate entries.

Note: A current restriction of the importer is that you must use a compatible scalar type when importing. For example, in order to import a matrix stored as integer in the matrix market format, you must import it as an integer matrix, otherwise a TypeMismatch error will be returned. This restriction may be lifted in the future, and is tracked by issue #1038.

Errors

See MatrixMarketErrorKind for a list of possible error conditions.

Examples

use nalgebra_sparse::io::load_coo_from_matrix_market_file;
// Use e.g. `i32` for integer matrices
let matrix = load_coo_from_matrix_market_file::<i32,_>("path/to/matrix.mtx").unwrap();
