I call cplex from Matlab, cplexmiqp and lp to be specific. The outputs are x,fval,exitflag and info . Info contains all sorts but not the intigrality gap if it was terminated due to time. That is shown in the command window if i select display , iter in the options. I need to know this gap.

Is there a method to: a) specify the gap to be added to the info cell? b) read the command window output? (I am aware that I could cheat via text files but the info written there must pass through somewhere fist, no?)

Obviously a solution along a) would be preferable.

I'm aware that this may not be the correct forum, but I've tried quite a few sources to no avail so far. Thanks in advance,
