Whenever you want to change the text label, just put this code

yourString = sprintf('The value = %f', someDoubleVariable); % or whatever you want.
set(handles.textLabel, 'String', yourString); % or whatever tag you have instead of "textLabel"
drawnow;  % Use draw now if in a fast loop.

It can go in whatever callback or loop you want, basically whenever and wherever you want to change the text on the label control.

% Create sample data.
x = -50 : 50;
y = sind(x*30);
plot(x, y, 'LIneWidth', 3);
grid on;
% Make x axis go from -10 to +30
% instead of -50 to +50:
xlim([-10, 30]);
% Give a label to the x axis:
xlabel('This is the x axis',...
  'FontSize', 20,...
  'FontWeight', 'bold',...
  'Color', [.7, 0.3, 0.9]);

You can use the Property Inspector if you use GUIDE (right click on the object whose properties you want to modify, select Property Inspector, look for the field to change in the emerging window).

Otherwise, you have to use set and get commands to perform changes in any object of your GUI.
