Download CVX 3.0 beta

Version 3.0beta, December 2017, Build 1183

Effective September 12, 2026, the download matrix below is no longer supported and will become completely unavailable very soon. Please migrate to the Releases page immediately, or even better, to Python and CVXPY.

Important note: This is prerelease software. We’ve worked hard to stamp out the big bugs, but of course we need your help to squash more! Here are some important notes:

• Versions 2.x and 3.0b cannot co-exist. Completely remove 2.x from your MATLAB path before you install 3.0b.
• You will have to re-run cvx_setup before using 3.0b. And if you decide to revert to version 2.x, you will have to re-run cvx_setup then, too.
• Your CVX Professional license will still work, but you will need to feed it to cvx_setup again. If you deleted your copy of the license, retrieve a copy here.
• An on-line copy of the updated documentation can be found here. The most significant changes
  can be found in the DCP ruleset section, due to the introduction of sign-sensitive convexity analysis.
• If you encounter an issue, don’t hesitate to submit a bug report by visiting our support page or sending an email to support@cvxr.com. Please make sure to indicate that you are using CVX 3.0beta; in fact, please include the entire output of cvx_version with your report.
