Dear fellows, I am using fmincon to do optmization. Could you tell me how to look at and store the intermediate result when fmincon is trying different value? Well, I need to give an initial value for fmincon to start, and after that, it will try different value to find the optimized one. I want to check all those values that it tried and the corresponding results. Cheers

You can use OutputFcn to access values at each iteration.
See the following link for more information:
In the optionset you can use the function as below:
options = optimset('OutputFcn',@outfun)

I am not sure I follow you. I don't want the final output.
Just run your optimization and and even if it is stuck at an iteration, can you please paste what is on the screen? If you post it in the forum there may be other who may be able to help you better. If you don't provide enough information, no one will be able to help you.

You can use my function outputFcn_global that saves all the intermediate results in a global variable, so you can inspect them later on.
