MATLAB GUI Edit Text and Static Text Objects Example

%Assume there is text_edit object which is called editext1.
%Assume there is a static_text object which is called statext1.

%Get the string in the text_edit object and convert it into a number n
n=str2num(get(handles.editext1,'string'));

%Do some thing with n
y=n*n;

%Convert y back into a string stry
stry=num2str(y);

%Set the 'string' field of the static_text object the string stry.
set(handles.statext1,'string',stry);
