Reference to non-existent field 'sol' issue with MOSEK V 8.1.0.34

[Reza Mohajerpoor]

Dear Johan

I am new in using YALMIP and MOSEK optimization toolboxes. I am solving a SDP problem in MATLAB using YALMIP toolbox and choosing MOSEK solver.
Unfortunately, I recieve the following error:

"Reference to non-existent field 'sol'.

Error in callmosek>MosekYALMIPError (line 241)
switch res.sol.itr.prosta

Error in callmosek>call_mosek_lpqpsocpsdpdual (line 213)
problem = MosekYALMIPError(res);

Error in callmosek>call_mosek_lpqpsocpsdp (line 81)
    [x,D_struc,problem,r,res,solvertime,prob] = call_mosek_lpqpsocpsdpdual(model);

Error in callmosek (line 51)
    [x,D_struc,problem,r,res,solvertime,prob] = call_mosek_lpqpsocpsdp(model);

Error in solvesdp (line 350)
    eval(['output = ' solver.call '(interfacedata);']);"

When using SDPT3 solver, I don't face with this problem and it gets solved successfully. I am not sure how to resolve this issue.
I have attached the m file and debug mat file attached for your reference.
This is a test code, and I will use MOSEK to solve a more controversial problem that SDPT3 is not capable of solving it.
I appreciate if you could help me out.

Best Regards
Reza

Is anything displayed before it crashes?

Does mosek work at all on your machine, and with yalmip?

Works here

Thank you professor for the reply.

I realised that the issue is from MOSEK, and is because I did not load the licence file for it in MATLAB. Now, the problem is resolved.

Hi Reza (or Johan),

Can you possibly provide me some help, encountering the same issue as you here.

I have added Mosek and all subfolders to the MATLAB path and have saved the license file in the base Mosek folder, and yet I still get the same error message for a very simple, feasible LP:

Reference to non-existent field 'sol'.

Error in callmosek>MosekYALMIPError (line 241)

switch res.sol.itr.prosta

Error in callmosek>call_mosek_lpqpsocpsdpdual (line 213)

problem = MosekYALMIPError(res);

Error in callmosek>call_mosek_lpqpsocpsdp (line 81)

    [x,D_struc,problem,r,res,solvertime,prob] = call_mosek_lpqpsocpsdpdual(model);

Error in callmosek (line 51)

    [x,D_struc,problem,r,res,solvertime,prob] = call_mosek_lpqpsocpsdp(model);

Error in solvesdp (line 350)

    eval(['output = ' solver.call '(interfacedata);']);

Error in optimize (line 31)

[varargout{1:nargout}] = solvesdp(varargin{:});

Is there anything else I need to do to get MATLAB to see the license file? Very confused by this.

Thanks a lot,

Jodie

So are you sure it is a license problem, i.e. what actually happens when you call mosek, such as any of their examples such as qcqo1

Running

  mosekdiag

inside Matlab is a good to check if MOSEK is working.
