Step-by-Step Guide to Plot Two Functions Together on the Same Graph in MATLAB

Are you trying to learn how to plot two functions together on the same graph in MATLAB? With the help of MATLAB's graph and plot functions, this task not only becomes easier but also gives an accurate and visually attractive graphical representation of your data. In this post, we will provide a step-by-step guide on how to plot two functions together on the same graph in MATLAB and provide some extra resources to help you in your learning journey.

Prerequisites

To plot two functions together on the same graph in MATLAB:

1. You should have a basic understanding of Functions, Graphs, and the MATLAB GUI
2. You must have MATLAB installed on your computer

Steps to Plot Two Functions Together on the Same Graph in MATLAB

Step 1: Determine the Domain

Before you plot the two functions together on the same graph, you should determine the length of the graph's x-axis. This determines the range of the x-axis that will appear in the graph. To plot two functions together on the same graph, the domains of the two functions must overlap.

Step 2: Enter the Functions Into MATLAB

Once you have determined the domain, you can enter the two functions into the MATLAB software. To plot two functions together on the same graph you should use MATLAB's Graph and Plot functions.

Step 3: Create the Graph

Once you have typed in the functions, you can create the graph. To do this, first select the Graph option from the MATLAB GUI. Then, enter the two functions into the “Function” box. Lastly, select “Plot Function” to plot the two functions together on the same graph.

Step 4: Adjust the Graph

Once you have created the graph, you can adjust it as desired. To adjust the x and y-axis, use the “Axes” option from the MATLAB GUI. Then, adjust the “Axes limits” to zoom in or out on the graph. To adjust the line styles, use the “Line Style” option.
