Hello Shawn,
I understand that you want to use the value of a text box in the GUI in another function. To do this, you can get a handle to the text box through the 'handles' structure and pass it as an input argument when you call the function.
For example, to get a handle for the text box (Tag : ‘txtbox1’), and passing it into the user function (say, userfunc), you can use the following lines of code:
hTxt = handles.txtbox1;
userfunc(hTxt);
Inside ‘userfunc’, you can get and set the value of the text box.
To get its value and store it in a new variable ‘c’,
c = str2num(hTxt.String);
To set its value to 45,
hTxt.String = num2str(45);
For more information, refer to this link:
I hope this helps!
