mark the end of a plot in a new colour in matlab

To mark the end of a plot with a new color in Matlab, you can use the plot function to plot a marker at the end of the plot, specifying the marker style and color.

Here is an example code snippet that plots a sine wave and marks the end of the plot in red:

main.m
% Sample data
x = linspace(-pi, pi, 100);
y = sin(x);

% Plot the data
plot(x, y);

% Mark the end of the plot in red
hold on;
plot(x(end), y(end), 'ro', 'MarkerFaceColor', 'r');
hold off;

In this code, we first generate some sample data (an array x of 100 values evenly spaced between -pi and pi, and an array y containing the corresponding sin values). We then use the plot function to plot the data, creating a curve.

After that, we use the hold on command to prevent any subsequent plots from overwriting this curve. We then use the plot function again to add a marker at the end of the curve, using the 'ro' argument to specify a red circle marker, and the 'MarkerFaceColor' attribute to fill the marker with red color. Finally, we use the hold off command to turn off the hold state so that any subsequent plots will start fresh.

The result of this code will be a plot of the sine wave with a red circle at the end, as shown below:
