How to plot points in MATLAB

You can plot points in MATLAB using the scatter function. The scatter function takes two arguments, representing the x-coordinates and y-coordinates of the data points.

For example, to plot the points (1,2), (3,4), and (5,6), you could use the following commands:

x = [1 3 5];
y = [2 4 6];
scatter(x, y)

In addition to the x- and y-coordinates, the scatter function also accepts a number of optional arguments that allow you to customize the appearance of the plot. For example, you can specify the color, size, and shape of the markers using the 'Color', 'SizeData', and 'Marker' properties.

Here is an example that creates a scatter plot with red markers of size 10 and square shape:

x = [1 3 5];
y = [2 4 6];
scatter(x, y, 'Color', 'r', 'SizeData', 10, 'Marker', 's')

You can also add labels, titles, and a legend to your scatter plot. For example, the following commands will add a title, axis labels, and a legend to the previous plot:

x = [1 3 5];
y = [2 4 6];
scatter(x, y, 'Color', 'r', 'SizeData', 10, 'Marker', 's')
title('Scatter Plot Example')
xlabel('x')
ylabel('y')
legend('data')

Conclusion

You can plot points in MATLAB using the scatter function. The scatter function takes two arguments, representing the x-coordinates and y-coordinates of the data points.
