constrained_lstsq_space Interface

public interface constrained_lstsq_space

Computes the size of the workspace required by the constrained least-squares solver. (Specification)

Description

This interface provides the size of the workspace array required by the constrained least-squares solver. It can be used to pre-allocate the working array in case several repeated solutions to a same system are sought. If pre-allocated, working arrays are provided, no internal allocation will take place.
