How to record all generations in Genetic Algorithms in MATLAB (R2012a)?

I am implementing Genetic Algorithm for my problem. The program needs many generations to reach the optima and I need to record the information of every generation in a text file or a variable (best function). I was wondering if there is any option in GA to record that for me?

The details can be accessed in a specified OutputFcns function. This is detailed in the following documentation page:

All the information you need, such as the population, the score of the current population, the current geneartion number, etc. - can be saved in the 'state' variable onto a file.
