Drawing 3D Surfaces Of Mathematical Equations In MatLab® Easily

The Use Of ‘ezplot()’ Command In Matlab® To Draw 2D Curves Efficiently

Another command in Matlab® to draw 2D curves from equations is the ‘ezplot()’ command. Besides conventional methods to draw 2D curves in Matlab®, ‘ezplot()’ is also a very useful alternative.

Here, we explain how to use the ‘ezplot()’ command to draw 2D curves in Matlab® with the very basic example below. The code example is executed in the Matlab® command window. So you can try it in your Matlab software. 

How To Use ‘ezplot()’ Command In MatLab®?

>> syms x
y = x^3+3*x+6;
ezplot(y, -10, 10)

Take a look at the code example above to understand syntax also. Firstly, we created a symbolic variable ‘x’ with the syms command. We can use this variable to create our functions or equations. 

Then we typed our equation according to Matlab® coding syntax and assigned it to ‘y’. 

In the ‘ezplot()’ command, we typed the ‘y’ and we defined the boundaries of your 2D curve in X and Y axes. You can see the result like below; 

Output curve.

You can edit this graph to a more illustrative shape by using Matlab® tools for it.


The use of the ‘ezplot()’ command in MatLab® is very simple like that.
