My program should have an interface where the user can choose the size of a square matrix from a popup menu, for example. According to that size, a table or a matrix-like structure should change its size in real time when a value is chosen from the menu. After the user inputs the values the matrix should be stored.
I just started to learn matlab and i stumbled upon what elements to use in order to visually recreate a matrix looking structure and how to make the connection between those elements and a popup menu. I would be very grateful if someone would give me some tips.
