Required Methods

unsafe fn lu(_: MatrixLayout, a: &mut [Self]) -> Result<Pivot>

Computes the LU factorization of a general m x n matrix a using partial pivoting with row interchanges.

If the result matches Err(LinalgError::Lapack(LapackError { return_code )) if return_code > 0, then U[(return_code-1, return_code-1)] is exactly zero. The factorization has been completed, but the factor U is exactly singular, and division by zero will occur if it is used to solve a system of equations.

unsafe fn inv(_: MatrixLayout, a: &mut [Self], _: &Pivot) -> Result<()>

unsafe fn rcond(
    _: MatrixLayout,
    a: &[Self],
    anorm: Self::Real
) -> Result<Self::Real>

Estimates the the reciprocal of the condition number of the matrix in 1-norm.

anorm should be the 1-norm of the matrix a.

    _: MatrixLayout,
    _: Transpose,
    a: &[Self],
    _: &Pivot,
    b: &mut [Self]
) -> Result<()>
