I have a program that results into either a TRUE or a FALSE... But in GUI, every time the result is TRUE, I need a static text to keep count and add 1 to itself per result of TRUE. How will I make this work?

Well what you'd do is set a counter variable that you keep track and increment whenever you get a true statement. then you can use the set() command to set the static text to

set(handles.text1,'String',['number of true: ' num2str(Truecounter)]);

What do you mean by counter variable? such as:

countM = countM + 1

like that?

I'm sort of new to this type of programming so your help is very much appreciated

yes, in whatever portion you are determining the outcome to be either true or false you'll have to setup a counter. such that in pseudocode:

 %X is whatever you're trying to find out if it is true or false
 if X>threshold
    outcome = true;
    numTrue = numTrue + 1;
    set text string to new numTrue value;
 else
    outcome = false;
 end

at the start of the gui you'd want to initialize the numTrue counter to 0. if you're using GUIDE, i'd suggest defining the counter in the handle structure as that is passed to each callback
