How to record mouse coordinates in fixed interval like 0.01ms?

The mouse cursor is free moving, and I have to record the mouse coordinates X and Y in fixed interval like 0.01ms to a txt or excel file. Could someone help me with this? Thanks!

Set up a timer that gets the PointerLocation property of the root graphics object.

Hi Walter, thank you for the help! I still can not figure out how to do this. Could you give me some example code? Thanks!

Note that the below uses nested functions. You will need to put it into its own .m file unless your other code has "end" matching each "function" statement.

function recorded_points = trackcursor01(how_many)

    recorded_points = [];
    t = timer('TimerFcn', @getCursor, 'ExecutionMode', 'fixedRate', 'Period', 0.01, 'TasksToExecute', how_many, 'StartFcn', 'disp(''Go! Go! Go!'')' );

    start(t);
    wait(t);
    stop(t);    %should not be necessary but should not hurt
    delete(t);

    function getCursor(src, event)    %nested function
      this_location = get(0, 'PointerLocation');
      recorded_points(end+1,:) = this_location;
    end

end
