I'm trying to install YALMIP on my new computer (windows x64), here the step i followed :
  1. Installed IBM CPLEX here: C:\ILOG\CPLEX_Studio125\cplex
  2. Installed Yalmip here: C:\Yalmip
  3. Added CPLEX and Yalmip to my Matlab path (and confirmed that all directories exist)
  4. I ran help cplexlp and getvalid output : cplexlp
    Solve linear programming problems....
    5. Also, which cplex gives this output : C:\ILOG\CPLEX_Studio1251\cplex\matlab\x64_win64\@Cplex\Cplex.p  % Cplex constructor
    6. which yalmip : C:\Yalmip\extras\yalmip.m
    7.I ran yalmiptest :

As a temporary fix, change the word 'cplexlink125' to 'cplexlink1251' in the file definesolvers.m

Your path is probably incorrect (note that cplex tries to call 12.4!)

which cplexlp -all

Should return something like C:\Program Files\IBM\ILOG\CPLEX_Studio1251\cplex\matlab\x64_win64\cplexlp.p and nothing else

This should work (entirely YALMIP free), otherwise your installation is broken
[x,fval,ex] = cplexlp(1,[],[],1,1)

Hi Raouf,

I have the same problem, and i have tried the same solutions. What I am getting is this

>> [x,fval,ex] = cplexlp(1,[],[])
??? Error using ==> cplexlp at 254
Undefined function or method 'cplexlink125' for input arguments of type 'struct'.

and of course my yalmiptest isn't finding the cplex too

Kindly, let me know

Most likely you have installed the 32bit version of cplex on a 64bit system

Dear Johan,
my cplex  version is 64 bit.
This has nothing to do with yalmip because  the following is not working also.

Nothing in the path indicates that you have a directory in the CPLEX directory which includes some kind of MATLAB interface. I don't know what the 12.2 directory structure looks like, but in 12.6 the matlab files are located in \cplex\matlab\x64_win64

You have either installed a version which doesn't have the MATLAB files, or you have setup the path incorrectly.

Either way, I would recommend you to install a more recent version of CPLEX: 12.2 is very old.

Cplex 12.6 works.
In fact before, it was Cplex 12.5 (64 bit. hundred percent sure!) installed and I do not know why it was an older version.
Anyway, thanks a lot for your help.

You contact TOMLAB support I guess if you have problem.

If you want to use YALMIP with CPLEX, just download cplex from their official site and make sure you are using the latest version of YALMIP.
