Use the MATLAB Help Browser to learn about the Current Point property of an axes object. Use this property to create a program that creates an axes object and plots a line connecting the locations of successive mouse elicks within the axes. Use the function wait forbuttonpress to wait for mouse clicks, and update the plot after each click. Terminate the program when a keyboard press occurs.

First, we need to create a figure and axes object in MATLAB. To do this, we will use the `figure` and `axes` commands: ```matlab fig = figure; ax = axes; ```

Next, we need to initialize variables to store the previous and current mouse click locations. We will also create an empty line object to store our plot. ```matlab prev_point = [NaN, NaN]; current_point = [NaN, NaN]; line_plot = plot(ax, NaN, NaN); ```

We will create a loop that will continuously wait for a button press (either mouse or keyboard). If it was a mouse click, the loop will get the current point in the axes and update the plot. If it was a keyboard press, the loop will break, and the program will terminate. ```matlab while true w = waitforbuttonpress; if w == 0 % It was a mouse click current_point = get(ax, 'CurrentPoint'); current_point = current_point(1, 1:2); % Get only the first row and the first two columns % Update the line plot xdata = get(line_plot, 'XData'); ydata = get(line_plot, 'YData'); xdata = [xdata, prev_point(1), current_point(1)]; ydata = [ydata, prev_point(2), current_point(2)]; set(line_plot, 'XData', xdata, 'YData', ydata); prev_point = current_point; else % It was a keyboard press break; end end ``` The complete code should look like this: ```matlab % Create a figure and axes fig = figure; ax = axes; % Initialize variables and plot prev_point = [NaN, NaN]; current_point = [NaN, NaN]; line_plot = plot(ax, NaN, NaN); % Loop to wait for mouse clicks and update the plot while true w = waitforbuttonpress; if w == 0 % It was a mouse click current_point = get(ax, 'CurrentPoint'); current_point = current_point(1, 1:2); % Get only the first row and the first two columns % Update the line plot xdata = get(line_plot, 'XData'); ydata = get(line_plot, 'YData'); xdata = [xdata, prev_point(1), current_point(1)]; ydata = [ydata, prev_point(2), current_point(2)]; set(line_plot, 'XData', xdata, 'YData', ydata); prev_point = current_point; else % It was a keyboard press break; end end ``` This program will create an axes object in MATLAB, and as the user clicks within the axes, the program will plot a line connecting successive mouse click locations. The program will terminate when the user presses a keyboard key.
