Struct LuWork 

pub struct LuWork<T> { /* private fields */ }

Buffers that LU factorizations reuse. A run of calls on matrices of one size allocates only in its first call.

Implementations

impl<T: Factor> LuWork<T>

pub fn factor(&mut self, a: &[T], n: usize) -> LuRef<'_, T>

lu of the n×n matrix a, held in these buffers until the next call.

pub fn solve(&mut self, a: &[T], b: &[T], size: [usize; 2], k: usize) -> Vec<T>

solve for the matrix a of size [m, n] and the m×k matrix b, using these buffers.

pub fn pinv_into(&mut self, a: &[T], size: [usize; 2], out: &mut [T])

pinv of the matrix a of size [m, n], written into out, which holds n×m items.

pub fn inverse_into( &mut self, a: &[T], size: [usize; 2], out: &mut [T], ) -> Option<T>

The inverse of the matrix a of size [m, n], written into out, and a’s determinant, from one LU factorization in these buffers. None, writing nothing, where a isn’t square or a pivot is negligible: where solve and pinv fall back to least squares.

Trait Implementations

impl<T> Default for LuWork<T>

fn default() -> Self

Returns the “default value” for a type.
