Dec 16, 2022 · MATLAB is a powerful programming language, that can be used to draw various plots used in machine learning, deep learning, computer vision, and big data programming. Let us start with coding for plots in MATLAB.
plot(X,Y) creates a 2-D line plot of the data in Y versus the corresponding values in X. To plot a set of coordinates connected by line segments, specify X and Y as vectors of the same length. To plot multiple sets of coordinates on the same set of axes, specify at least one of X or Y as a matrix. example.

To create two-dimensional line plots, use the plot function. For example, plot the sine function over a linearly spaced vector of values from 0 to 2π: You can label the axes and add a title. By adding a third input argument to the plotfunction, you can plot the same variables using a red dashed line. "r--" is a line specification. Each specificatio...
Three-dimensional plots typically display a surface defined by a function in two variables, z=f(x,y). For instance, calculate z=xe−x2−y2 given row and column vectors x and ywith 20 points each in the range [-2,2]. Then, create a surface plot. Both the surf function and its companion mesh display surfaces in three dimensions. surf displays both the ...
You can display multiple plots in different parts of the same window using either tiledlayout or subplot. The tiledlayout function was introduced in R2019b and provides more control over labels and spacing than subplot. For example, create a 2-by-2 layout within a figure window. Then, call nexttileeach time you want a plot to appear in the next reg...
In MATLAB, this interactivity can be achieved using functions such as ‘plot’, ‘figure’, and ‘uiobjects’. By following a few simple steps and understanding the basics of interactive plotting, users can create engaging and dynamic plots that provide valuable insights into their data.
An exploratory plot of your data enables you to identify discontinuities and potential outliers, as well as the regions of interest. The MATLAB figure window displays plots. See Types of MATLAB Plots for a full description of the figure window.
Mar 22, 2024 · Key Points. Use plot (vector) to visualize data in the y axis with an index number in the x axis. Use plot (X,Y) to specify values in both axes. Document your plots with title ("My title"), xlabel ("My horizontal label") and ylabel ("My vertical label"). Use hold on and hold off to plot multiple lines at the same time.
Get started quickly with the basics of MATLAB. Plot vectors and matrices of data with different types of visualizations, including line plots, scatter plots, bar plots, and histograms. Learn common customization and annotation techniques in MATLAB.
