Hello I have installed yalmip. Then i checked that it works through writing yalmip in the command window , and it gives : yalmip yalmip Returns various information about yalmip
yalmip can be used to check version numbers and
find the SDPVAR and SET objects available in workspace
EXAMPLES
V = yalmip('version') % Returns version
yalmip('nvars') % Returns total number of declared variables
yalmip('info') % Display basic info.
yalmip('solver','tag') % Sets the solver 'solvertag' (see sdpsettings) as default solver
If you want information on how to use yalmip, you are advised to check out

You must have failed with the installation such as unzipping and/or setting the path. Show us your path, and a "dir" performed in the yalmip directory

The commend run like
constraint_ml = set(cone(zz,y2));
, and an error comes. Could please help me to solve this problem.
"SET has been considered obsolete for many years, and the time has come...
Update your code. https://yalmip.github.io/tutorial/basics/
wrong use constraint/set
Obsolete command"
