How can I access the population matrix generated by genetic algorithm??..

I am working in MATLAB 2012a...

I want to access the initial population generated for genetic algorithm... I have set all the options in option structure i.e. population type, size,creation function etc..

But now I want to see the population that is actually generated after setting all the above options..... How can I do that??.. How can i see that population in the form of matrix??...

Actually, I need to save the population and have to use it in some other .m file, but unable to access that population

can someone plz help me out??....
