Version 2.2, January 2020, Build 1148

Please note:Despite the similar name, CVX Research, Inc. does not develop or support the R package called cvxr. The offerings below are strictly for the MATLAB package only.

Important note: CVX is not supported on Octave, and we unfortunately do not have the bandwidth to help you make it work. But this post on the CVX Forum is collecting some initial user progress.

For most users, a Standard bundle will be the right choice. These include all of the supported solvers available for your platform.

The Redistributable bundle is appropriate if you do not intend to use a commercial solver, or if you wish to distribute CVX with your application, under the CVX Standard License (v2.0) or the GPLv2 (v1.22).

The Commercial bundles are appropriate for organizations that are sensitive to the use of GPL-licensed software. These bundles do not include the solvers SDPT3 or SeDuMi, which are subject to the GPLv2 license and are included with CVX with permission.

Still using 32-bit Linux or Windows? Unfortunately, we can no longer support these older platforms, and our commercial software vendors are dropping support as well.

Please note that the use of Gurobi and MOSEK require a CVX Professional license key. In addition, Gurobi requires a separate license key obtained directly from Gurobi Optimization. Without these licenses, the Full package still provides full functionality with the free solvers SeDuMi and SDPT3, so there is no harm in downloading the Full package even if you do not intend to use the commercial solvers.

Installation instructions

For most platforms, installation is relatively simple: unpack the distribution to an empty directory, and then run cvx_setup from the MATLAB command line. Do not add CVX to your path yourself; let cvx_setup do it for you. Full instructions can be found in the Installation section of the users’ guide, found here online or included with the distribution in the doc/ subdirectory.

We have created two separate sections in the users’ guide for using CVX with Gurobi and MOSEK. These sections include special instructions for connecting external installations of Gurobi and MOSEK to CVX, and instructions on licenses.

Licensing and redistribution

CVX is free for use in both academic or commercial applications when paired with one of the free bundled free solvers, SDPT3 or SeDuMi. A CVX Professional license is required to use CVX with the commercial solvers Gurobi and MOSEK. Academic users can obtain a license key at no charge. For more information, visit the Licensing page. The use of Gurobi also requires a license key from Gurobi as well; again, academic users can obtain such a key free of charge.

Each of the packages above come with different licensing conditions; please see the license page of the documentation
for more details. A brief summary:

• The Full and BYOS packages may not be redistributed without the advance written permission of CVX Research, Inc.
• The Redistributable packages for version 2.x are subject to the terms of the CVX Standard License, which is a minor
modification of the GNU General Public License, Version 3.
