solve quadratic minimisation subject to inequality constraints
This is an abstract class to allow you to define a generic quadratic minimisation problem with upper and lower limits on the element values. When the qpBox class is inherited, you specify two functions (hCalc and fCalc) which calculate the H and f matrices based on whatever inputs (and additional properties) you choose.
Since it is a matlab.System class, it can be run in MATLAB or Simulink (it was originally written to solve a control problem in Simulink where the H and f matrices change over time): examples are provided for both. the built-in MATLAB solver quadprog cannot be implemented in Simulink, and also has a lot of overhead so will typically run slower.
