(I rewrite my question here as I was not able to attache the instruction file in the previous one).

Thanks you so much. It has been a long time that I was looking for this instruction.
I tried to install the Cplex-Matlab interface but I have a problem and I really don't know what the solution is. I already asked my colleagues and I found that they also had the same problem several times.
Attached is the instruction which I followed to install the CPLEX-Malab interface and the mentioned error is as below: (it should be mentioned that this instruction is the one which my colleagues already used and most of them didn’t have any problem to install the CPLEX 12.1)
Would you please do me favor and help with this problem as well.

Sincere appreciation in advance,
Masood

except cplexgui.m, how about other examples? Do they work?

Really thanks for replying me. I tried to run another example and following is the Error.
(Note:I got a new license through the IBM website three days ago)

??? Error using ==> Cplex.Cplex at 746
CPLEX Error 32201: ILM Error 16: CPLEX: license file not found or unreadable.

Looks like a license issue, did you install our license correctly? Maybe you need to take a look the license doc.

I followed the below instruction,I also found a link on IBM website which is really helpful (http://download.boulder.ibm.com/ibmdl/pub/software/dw/university/support/ILOGQuickStart.pdf)and I instilled the CPLEX again. luckily, the license problem is solved and I solved my problem using the new version (12.3) in 8.84 sec.. However, I still have the same problem with "cplexgui".

Instruction:

Install cplex (32 bit version)
Copy ILM folder into ILOG folder
Open Matlab. Go to File->Set Path…->Add with Subfolders…->(ILOG folder)
It should work now. Try “cplexgui” command. A user interface should appear.
If Cplex doesn’t work, try setting the following environmental variable.
In Windows: Go to Control Panel->System->Advanced System Settings
Click on “Environment Variables…” and select new
Variable name: ILOG_LICENSE_KEY or ILOG_LICENSE_FILE
Variable value: path of ILM folder

what's wrong with it?
every time I run

>> cplexgui

the error will be like this

could you help me solve this problem?
thanks a lot.

Thanks for pointing out this. Looks like a bug in cplexgui example.
But which is an example bug only, don't effect Cplex class and toolbox functions.

Thanks for your response. I have solved several examples and it seems that there isn't any problem with CPLEX (The only problem is "cplexgui" example).

I get the same error:

Also, I get the same error if I try to open cplexgui.fig directly in MATLAB.

Is there a new uncorrupted version of cplexgui.fig?

Sorry, that is in the fixpack of 12.4, you have to wait for this.

Or if you have the old version CPLEX, say cplex122, cplex121, then you can just copy the file as a workaround.

The fixpack for CPLEX 12.4 should now be available here.
