Function invert_lower_in_place

    E: ComplexField,
Expand description

Computes the lower triangular part of the inverse of a matrix, given its Cholesky decomposition, and stores the result in cholesky_factor.

ยงPanics

  • Panics if cholesky_factor is not a square matrix.

This can also panic if the provided memory in stack is insufficient (see invert_lower_req).
