mohadeseh - one way (and there may be another) is to create a figure and have that figure capture the mouse button events (assuming the mouse pointer is hovering over the figure). For example, code like
function MouseButtonExample
close all;
hFig = uifigure;
set(hFig,'WindowButtonDownFcn',@ButtonDown);
hLabel = uilabel(hFig);
hLabel.Position = [0 0 hFig.Position(3) hFig.Position(4)];
hLabel.Text = 'Press the Left or Right Mouse button when you hear the sound in the corresponding ear.';
hLabel.HorizontalAlignment = 'Center';
leftButtonCount = 0;
rightButtonCount = 0;
function ButtonDown(hObject, eventdata)
mouseSelectionType = hFig.SelectionType;
if strcmp(mouseSelectionType,'normal')
leftButtonCount = leftButtonCount + 1;
elseif strcmp(mouseSelectionType,'alt')
rightButtonCount = rightButtonCount + 1;
end
fprintf('leftButtonCount = %d\n', leftButtonCount);
fprintf('rightButtonCount = %d\n', rightButtonCount);
end
end
would count the number of left button clicks and right button clicks given the Figure SelectionType property. This may be sufficient to allow you to assign the mouse button (1 or 2) to the X matrix. In order to integrate the above, you will probably want to convert your above code from a script to a function so that you can nest the callback within that main function (like how I nest ButtonDownCallback within the main MouseButtonExample function.
