title: MATLAB GUI - bring up a string
body: <p>i' m try to create a simplex and fast gui on matlab. I made a button with a callback function, but I don' t know how to bring up a string that depends upon the result of the function. For example if the result of the function is 1, must appear the string "All ok!", if the result of the function is 0, must appear the string "It' s wrong!!!".</p>
