YALMIP is entirely based on m-code, and is thus easy to install. Remove any old version of YALMIP, unzip the file YALMIP.zip and add the following directories to your MATLAB path
A lazy way to do this is addpath(genpath(yalmiprootdirectory))
If you have MPT installed, make sure that you delete the YALMIP distribution residing inside MPT and remove the old path definitions.
If you have used YALMIP before, type clear classes or restart MATLAB before using the new version.
The solvers should be installed as described in the solver manuals. Make sure to add required paths.
To test your installation, run the command yalmiptest. For further examples and tests, run code from this Wiki!
If you have problems, please read the FAQ.
YALMIP is primarily developed on a Windows machine using MATLAB 7.12 (2011a). The code should work on any platform, but is developed and thus most extensively tested on Windows. Most parts of YALMIP should in principle work with MATLAB 6.5, but has not been tested (to any larger extent) on these versions. MATLAB 5.2 or earlier versions are definitely not supported.
