Error message when using checkset

[Marcio]

Hello everyone,

I am solving a problem with five polynomial matrices constraints using SOS. 

I am using yalmipversion: '20200116' and Matlab R2014a.

The problem is solved with sedumi by using sol = optimize(F,obj,sdpsettings('verbose',0,'solver','sedumi'),[Vetv]);

Vetv is a linear matrix variable. Apparently, the problem is solved and I can recover the solution by using value(Vetv).

However, when I use checkset there is an error message and I did not find the problem that is occurring.

I have four constraints (symmetric polynomial matrix variables) with dimension 2x2 and one constraint 3x3.

When I remove this last constraint the problem does not occur.

>> checkset(F)

 

Error using sdpvar/vertcat (line 31)

All rows in the bracketed expression must have the

same number of columns.

Error in lmi/check (line 79)

            p=[p;pi];

Error in lmi/checkset (line 27)

        check(F);

Thanks in advance,

Supply a reproducible example

Confirmed. I've checked in what I think is a fix on the develop branch

Thank you. Is there any alternative to check if the solution is reliable?
