fmincon save each iteration information

I am using the fmincon, and I want to save the fitting value for each iteration automatically. What I can do is to display the fmincon information when the process is done using the optimset('display','iter'). But I could not find a way to save the value of obj function input in each iteration. Could anyone help to solve this problem?

Use an output function to record whatever you like. This example records the history of the locations and the objective function value; modify it as you like.
