The subplot command is used for creating subplots. When you create an array of plots in the same figure, each of these plots is called a subplot. When you run the file, MATLAB generates the following graph − Generating Sub-Plots The following example shows this − Example
You can provide minimum and maximum values for x and y axes using the axis command in the following way − The axis command allows you to set the axis scales. When you run the file, MATLAB generates the following graph − Setting Axis Scales

The following table shows the colors and their codes − Code MATLAB provides eight basic color options for drawing graphs. MATLAB generates the following graph − Setting Colors on Graph The following example demonstrates the concept − Example You can draw multiple graphs on the same plot. MATLAB generates the following graph − Drawing Multiple Functions on the Same Graph The axis square command generates a square plot. The axis equal command allows generating the plot with the same scale factors and the spaces on both axes. The grid on command allows you to put the grid lines on the graph. The title command allows you to put a title on the graph. The xlabel and ylabel commands generate labels along x-axis and y-axis. MATLAB allows you to add title, labels along the x-axis and y-axis, grid lines and also to adjust the axes to spruce up the graph. MATLAB draws a smoother graph − Adding Title, Labels, Grid Lines and Scaling on the Graph Please note that as we decrease the increment, the graph becomes smoother.Ĭhange the code file a little, reduce the increment to 5 − In this example, we will draw two graphs with the same function, but in second time, we will reduce the value of increment. Let us take one more example to plot the function y = x 2. When you run the file, MATLAB displays the following plot − Let us plot the simple function y = x for the range of values for x from 0 to 100, with an increment of 5.Ĭreate a script file and type the following code − If you have done programming in any other high-level programming language like C, C++ or Java, then it will be very much beneficial and learning MATLAB will be like a fun for you.To plot the graph of a function, you need to take the following steps −ĭefine x, by specifying the range of values for the variable x, for which the function is to be plottedįollowing example would demonstrate the concept. We assume you have a little knowledge of any computer programming and understand concepts like variables, constants, expression, statements, etc. Freemat provides visualization, image manipulation, and plotting as well as parallel programming. After completing this tutorial you will find yourself at a moderate level of expertise in using MATLAB from where you can take yourself to next levels. Freemat is an interpreted, matrix-oriented development environment for engineering and scientific applications, similar to the commercial package MATLAB. This tutorial has been prepared for the beginners to help them understand basic to advanced functionality of MATLAB. Problem-based MATLAB examples have been given in simple and easy way to make your learning fast and effective. It is designed to give students fluency in MATLAB programming language. This tutorial gives you aggressively a gentle introduction of MATLAB programming language. It can be run both under interactive sessions and as a batch job. It started out as a matrix programming language where linear algebra programming was simple. MATLAB is a programming language developed by MathWorks.
