so what's the problem with MATLAB and mipex3.m?

Thanks for posting, but I can not reproduce on my machine, and also, mipex3 only support 'r', 'c', 'n' 3 options, could you please try these options?

And also, could you help me to reproduce this issue? such as please tell me:
1. which OS are you using? 32bits windows xp?
2. which version of CPLEX are you using? 12.2 or 12.3?
3. once you start matlab, you typed mipex3('a') or after run some other programs then run mipex3('a')?

64 bits windows 7

CPLEX 12.3
3. once you start matlab, you typed mipex3('a') or after run some other programs then run mipex3('a')?
after run some other programs then run mipex3('a')
I also encounter the matlab internal problem when I run other code besides the mipex3.m.
I don't what's the problem with matlab or cplex.

OK, then could you please only run mipex3 after matlab started, to make sure not mipex3 caused the problem?

excuse me, I encountered this problem again. this time I was using windows 7 64 bits, cplex 12.4,

and I tried the code as follows

[x,fval,exitflag,output] = cplexmilp(f,Aineq,bineq,[],[],[],[],[],lb,ub,ctype,[],[] );

but the problem occurs as

matlab has encountered internal problem and needs to close

I don't know why.

It can run normally now.
I think it's because I'm using cplex 12.2 when run the mipex3.m which is included under the directory of cplex 12.3
