BARON logsumexp error

[Aras]

Hi Everyone, and Dr. Lofberg,

I am running the following:

x = sdpvar(n,1);

Constraints = [D*x <= d, x>=0 ];

Obj = logsumexp(A*x);

P = optimize(Constraints, -Obj, sdpsettings('debug',1,'solver', 'baron'));

and getting the following error(s) due to the usage of logsumexp (which was not an issue with KNITRO or IPOPT):

Error using baron

There was an error evaluating a user supplied function. Please examine the below error and correct your function.

Error using "logsumexp" (line 47)

SDPVAR/LOG called with CHAR argument?

Error in Ipopt (line 10)

Is this due to Yalmip, or am I doing some big mistake? 

Thank you!

True, fixed and pushed to develop branch

[Aras]

does 'develop' mean I can fix this if I re-install yalmip latest version? Thanks!

[Aras]

Because I installed Yalmip again and it is not fixed. Most probably I need to do more..

Installed the same from https://github.com/yalmip/YALMIP/tree/develop

Now it works.

Many thanks!
