Yalmip Error - LMI Not Available

[S]

In Matlab, I'm getting an error that I'm not sure about and can't seem to find (from Google searches) any information on.

When I try to run Yalmip's solvesdp:

options = sdpsettings('verbose',2,'warning',1,'showprogress',1,'savesolverinput',1,'savesolveroutput',1,'solver','IPOPT');

sol = solvesdp(constraints,objective,options);

 I get...

Error using lmi/subsref (line 44)

LMI #227 not available.

Error in compileinterfacedata>convertsocp2NONLINEAR (line 1232)

        z = sdpvar(Fsocp(i));

Error in compileinterfacedata (line 699)

                [F,changed] = convertsocp2NONLINEAR(F);

Error in solvesdp (line 241)

[interfacedata,recoverdata,solver,diagnostic,F,Fremoved] =

compileinterfacedata(F,[],logdetStruct,h,options,0,solving_parametric);

Error in RunOptimizer (line 126)

sol = solvesdp(constraints,objective,options); 

I've also tried this with Matlab's fmincon solver, and I get the same error.  Any one know about this?

Thanks!

I am pretty sure you are running an old version of YALMIP. This was supposed to have been fixed in R20121126.

I am using Yalmip Release 20121126.  I've tried this with Matlab 2012a (32-bit) and Matlab 2012b (32-bit).  Please let me know what other information I can provide to help debug this.

Also I'm using Windows XP.

No, you are running R20120926. Line 1232 in R20121126 looks like this

Fout = [Fout,lambda(0+1) <= r(1), sum(r)==1];

your error message says

Error in compileinterfacedata>convertsocp2NONLINEAR (line 1232)

       z = sdpvar(Fsocp(i));

which exactly what line 1232 looks like in R20120926.

Thanks for the follow up.  I checked \yalmip\extras\compileinterfacedata.m, and line 1232 is what it should be for R20121126.  I no longer get that error, and I'm pretty sure I didn't change anything, so I really don't know what was up with that.  I am running in to another error though, and I'll post that in a new thread if I can't figure it out.

Thanks again for your help!
