Hello I'm writing a code that should find optimal solution for distribution of air pollution sensors. I'm using 'intlinprog' solver that it's best suit for mixed integer linear program. All my Variable are set to be binary (integers that limited from 0 to 1) but i have a lot of them, 20100 variables, so it take my computer time to compute solution. i ran the solver for about an hour and still no result. I wish to track the iterations the solver make in order to understand if there is any problem during the run.
I found documentation that give example how to plot the solutions during iterations but if failed to work http://www.mathworks.com/help/optim/ug/intlinprog-output-functions-and-plot-functions.html
The line i used is the following:
options = optimoptions(@intlinprog,'PlotFcns',@optimplotmilp)
[x,fval,exitflag,output] = intlinprog(f,intcon,A,B,Aeq,beq,lb,ub,options)
And the error i get is 'PlotFcns' is not an option for INTLINPROG.
I'm using Matlab R2014a
Thank you Or Hirshfeld אור הירשפלד

The PlotFcns option was introduced in R2014b, see
If you can upgrade, that would be the simplest solution.

Workaround without upgrading? I don't think so. Other than the Display option, my best recommendation is that you use the MaxGenerations, MaxIter, or MaxTime options to abort the Optimization at a point where you think it should be showing reasonable progress.
