Late answer but anyway...

1. Why have you installed such an old version? 12.6 has been out for a long time now

2. This error typically occurs when people install a 32bit version of CPLEX on a 64bit system. To see what you should have, run the command mexext i MATLAB. If it says mexw64, you should install 64bit CPLEX, and mexw32 means you need 32bit version (Assuming you are on Windows)

thank you very much for the answer. and my problem was solved by installing a new version of matlab

did you solve before a linear program with matlab using the cplex labrery ?

thanks
