Products of vectors (qics.point)ΒΆ

This module contains classes which are used to represent vectors which lie in Cartesian products of vector spaces, including

  • Real vectors \(\mathbb{R}^n\)

  • Symmetric matrices \(\mathbb{S}^n\)

  • Hermitian matrices \(\mathbb{H}^n\)

These classes contain a vec attribute which is the column vector representation of variable (see Representing matrices), and we use numpy.ndarray.view to link different parts of vec to different variables. This allows us to perform efficient vectorized NumPy operations on our vectors, while easily being able to access the different variables contained within the vector.

Point(model)

Vector containing the variables involved in a homogeneous self-dual embedding of a primal-dual conic program

VecProduct(cones[, vec])

Cartesian product of vectors corresponding to a list of cones
