# Alternative 3D Surface Drawing Command In MatLab®: ezsurf()

There are various ways to draw 3D surfaces in Matlab® efficiently. One of them is the ‘ezsurf()’ command which is also a very efficient way to draw 3D surfaces. Here, we explain how to draw 3D surfaces with the ‘ezsurf()’ command in Matlab® with a very basic code example below. This code is executed in the Matlab® command window to obtain the output surface below.

## How To Use ‘ezsurf()’ Command In Matlab®?

``ezsurf('y^3+x^3+3*x+6',[-100,100],50)``

Look at the code example about the ‘ezsurf()’ command to understand the syntax of it. First, we created our polynomial or equation with a random letter say ‘x’ here. This ‘x’ is a symbolic variable here. Type your equation inside quotes.

Then define the boundaries of ‘X’ and ‘Y’ plotting axes after the equation like above. Square brackets are very important. Then define the number of grids at last which is ’50’ here.

The output surface is;

## Conclusion

So, drawing 3D surfaces with the ‘ezsurf()’ command in Matlab® is very simple.
