How can I create a multiple screen GUI in MATLAB?

Thank you Mr. Sherif for your answer. I have tried the way you said, the second GUI is running. But I donot need a second GUI, instead I want to clear (make it invisible) the whole data on the GUI and display new data on the same GUI...........for example, I have some static text on GUI....now pressing a button should display a new static text by clearing off the old one........

If the second GUI is defined with GUIDE, just have the submit button callback invoke the second gui name as a function -- pretty much the same way that you started the initial gui by invoking its name as a function.
