fmincon, MaxFunctionEvaluations and out of memory

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

[Walter Roberson]

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

Answer 1

[Hessam Fathipour]

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

[Walter Roberson]

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?
