Struct LqDescriptor

    pub m: usize,
    pub n: usize,
    pub a: &'a [T],

Thin LQ decomposition descriptor: A = L * Q

Computes the thin LQ of an m×n matrix A. Data layout (A, L, Q slices) is specified by the order field; a backend that does not support a given order returns BackendError::InvalidArgument. Outputs: L (m×k), Q (k×n) where k = min(m, n).

Fields

m: usize

Rows of A.

n: usize

Columns of A.

a: &'a [T]

Input matrix A (m×n).

l: &'a mut [T]

Output lower-triangular factor L (m×k, k = min(m, n)).

q: &'a mut [T]

Output orthonormal factor Q (k×n).

order: MemoryOrder

Memory layout of the matrix slices.

policy: ExecPolicy

Per-call execution policy.
