static variables in matlab?

basically i have a GUI for image compression , in which i need to plot a graph for input values(quality) and output(PSNR), but i need minimum of 5 values, as i tried to store the inputs and outputs in an array it stores only the current execution values but i need to retain the values of all other previous inputs and outputs. is there a way to achieve this?

Pradeep - if you are using GUIDE to create your GUI, then you can use the handles structure, with the appropriate calls to guidata, to store your data. Else consider using persitent to retain the value of local variables between calls to the function where these variables have been declared.

Thanx , but i used global variables and got solution. I know using global variables is not efficient but i gave it a try , it worked.
