CVXQUAD is a collection of functions to be used with the MATLAB-based convex optimization toolCVX. It augments CVX with various convex/concave functions based on matrix logarithm such as the von Neumann entropy, or the quantum relative entropy (see below for list of functions). This package is...
Note: As we mentioned, modeling systems for convex optimization that are based on SDP solvers, such as CVX, have to use approximation for functions involving exp and \(\ln \). Approximation makes it hard to return dual certificates, specifically when the problem is infeasible or unbounded. 1.8...

If the target "language" is "cvx", we will generate a single Matlab file that contains the CVX-equivalent problem. Data structures In this section, we document the data structures used for each language. The input of prob2socp is a dictionary/struct containing the parameters. No sign checkin...
