The function has the following syntax, where Y is plotted with the corresponding X values. Use the function “plot” to create a 2D line plot of the function declared in Step 2. Y=exp(x) Step 3: Use the plot function to generate a figure Declare an exponential function using the following expression. Any variable name can be used in place of “y”, however “y” is often the standard. Step 2: Define the function, y = f(x)ĭeclare the desired function with the “=” operator. If your graph isn’t a smooth plot, it’s likely that the number of points needs to be increased. MATLAB Figure: sin(x) with 100 values plotted However, if linspace(0,10,100) is used to generate 100 points instead of 10, the figure below is produced. MATLAB Figure: sin(x) with only 10 values plotted Plotting the function y=sin(x) with the range of values set as linspace(0,10,10) would result in the figure below: Having too few points will result in graphs that are inaccurate. X has the following values in this sample: The distance between the points can be calculated with the equation (x2-x1)/(n-1).įor example, the following code will have a distance of (10-0)/(10-1)=1.1111 between each point and have 10 points between 0 and 10. The “linspace” function generates “n” number of points between x1 and x2.

Specify the range of values as a linearly spaced vector with the “linspace” function. Screenshot: Create a script in MATLAB 2019a Step 1: Specify the Range of Values for the x variable for which you’re plotting the function. To create a new script, select the icon in the top left corner to begin.

Whether you’re learning about MATLAB for the first time or want a refresher, here’s a brief tutorial on plotting graphs, as well as adding labels and a title, plotting lines, scaling on the graph, and more. Getting to know MATLAB involves understanding various mathematical concepts, and learning how to plot a graph in MATLAB is one of those concepts at play. MATLAB is one of the more complex numerical computing and programming platforms.
