qpalm::Data Class Reference

#include <qpalm.hpp>

Detailed Description

Stores the matrices and vectors that define the problem.

$$\begin{array}{rlrl}& \underset{x}{\mathrm{minimize}}& & \frac{1}{2}{x}^{\mathrm{\top }}Qx+q^{\mathrm{\top }}x+c\\ & \text{subject to}& & b_{\min }\le Ax\le b_{\max }\end{array}$$
