    Hi,all

    I use the cplex 12.1 via the matlab interface.I am using toolbox functions. I want to set a bigger gap than the default value to accelerate the computational speed.S0 I use the statements below. But it does not work. how can I set new gap for the convergency criterion of cplex.

    options = cplexoptimset ('cplex');
    options.Diagnostics = 'on';
    options.mip.tolerances.mipgap=0.003;

    How about just set options.mip.tolerances.mipgap=0.003; only in our code?
    BTW, if you are an acedemic user, I suggest you upgrade to CPLEX 12.4, we improved a lot in CPLEX 12.4
