pub fn invert_in_place<E>(
    qr_factors: MatMut<'_, E>,

Expand description

Computes the inverse of a matrix, given its QR decomposition, and stores the result in qr_factors.

§Panics

Panics if qr_factors is not a square matrix.
Panics if the number of columns of householder_factor isn’t the same as the minimum of the number of rows and the number of columns of qr_factors.
Panics if the block size is zero.
Panics if the provided memory in stack is insufficient (see invert_in_place_req).
