Saving the design variable's history in optimization

I'm using the global optimization tools ga and sa. Now, I want to have the history of the changes made in the design variables, not in a plot but in a text file which contains the values of the variables at each iteration. How can this be done?

This can be done easily using an Output Function. The documentation for ga is here, and the documentation for sa is here.
Basically, at each stage in the algorithm, append the current point to a matrix, such as with the command
xhistory = [xhistory;x];
There is an example here showing how to use output functions for a similar purpose, but be careful because this solver uses a different syntax.
