When I increasing manually the "MaxFunctionEvaluations" in fmincon, optimization stopped because of "out of memory". How can I fix it?

I would not tend to expect that unless your objective function is saving data to memory, or in certain cases involving OutputFcn or PlotFcn ?

it's that error I mentioned:
Error using ldl
Out of memory. Type "help memory" for your options.
Error in formAndFactorKKTmatrix
Error in computeTrialStep
Error in barrier

Are you using OutputFcn or PlotFcn or saving data to persistent memory or global variables?
Are you using a lot of input variables? Possibly enough that without the increasing in function evaluations, it cannot estimate the gradient even once, so increasing the maximum function evaluations might be permitting it to proceed further than it would otherwise?
