We need to see your code for the GUI, and how you input your data.

You have to know the "tag" of the edit field. Let's say you called it editPH. So then whenever you need this string in that edit box, you do this:

P_h = get(handles.editPH, 'String');

If you need it to be a number then

P_h = str2double(P_h);

Of course you should do some validation on the string to make sure they only types in valid numerical symbols 0-9 plus minus sign and period, before you call str2double().

thank you a lot it worked , what about the run button, how can i make it as a trigger for my m file ?

I don't know what you mean. Just put whatever code you want into the callback for the pushbutton. Attach your .fig, .m, and data files if you want more help.
