I'm trying to collect information (car specifications) through a dialog-box, and then save this into a file/profile or something. So when you run the script a dialog-box pops up and you get to fill in blanks and then the script will put this information into a file and save this. Thereafter matlab will spit out all the data which can be calculated with the given information. Can someone explain me how to get matlab to save user input in a file, and how to recall this later? I'd be very thankful for your help.
