Looks like you have TOMLAB installed, and I would not be surprised if TOMLAB has some cplex interface of their own, which uses the same name as the cplex interface supplied by IBM in the recent CPLEX versions (i.e., check where the file cplexlp (>>which cplexlp) is located)

Remove TOMLAB from your path and it should work.

Hi Johan,

I have installed the latest YALMIP with CPLEX12.1. When I run "yalmiptest" I get the following message:

and when I run "which cplex" I get the following:

C:\ILOG\CPLEX121\matlab\x64_win64\@Cplex\Cplex.p % Cplex constructor

Could you let me know what is the problem and is there any solution ?

Thank you in advance

Restart MATLAB (as it could be some weird fault in your work-space) and try to see the error more clearly by solving a specific problem with debug on

sdpvar x
solvesdp(x>=0,x^2,sdpsettings('solver','cplex','debug',1))

You should update cplex. I haven't worked with 12.1 in a long time.

Here is the error when I run the code you have sent me:

Error using cplexqp (line 186)

I presume you've checked that cplex actually works

>> cplexqp(1,1,1,6)

ans =

    -1

No, it does not work. I get this error

So then you have to fix that first.

You either have a very old MATLAB version, or your cplex installation is borked.

I have "MATLAB R2014a". Could the problem be because of new MATLAB and old CPLEX12.1 ? or I should look for a solution in CPLEX installation ?

You should update cplex in any case. It is old.
