Struct LuFactors 

pub struct LuFactors {
    pub lu: Matrix,
    pub ipiv: Vec<i64>,
    pub info: i32,
}

An LU factorization A = P L U computed by lapack_dgetrf.

Fields

lu: Matrix

L (below the diagonal, unit diagonal not stored) and U (on and above the diagonal), packed in one matrix of the shape of A.

ipiv: Vec<i64>

Pivot indices, one-based as in LAPACK: row i was interchanged with row ipiv[i] - 1.

info: i32

LAPACK’s info: 0 on success, i > 0 if U(i-1, i-1) is exactly zero (the factorization is complete, but U is singular).

Implementations

impl LuFactors

pub fn is_singular(&self) -> bool

Whether U is exactly singular.

pub fn solve(&self, transpose: bool, b: &Matrix) -> Result<Matrix>

Solves A X = B (or A' X = B if transpose) with these factors, see lapack_dgetrs.

Trait Implementations

impl Clone for LuFactors

fn clone(&self) -> LuFactors

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LuFactors

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for LuFactors

fn eq(&self, other: &LuFactors) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
