Drawing The Graphs Of Polar Functions In MatLab®

Like cartesian coordinate systems, the polar coordinate system is also a very important aspect of mathematics. Some of the functions in lots of applications can be defined in polar coordinates or polar form. Matlab® offers a very useful command to plot these polar functions. The command that does this thing is called as ‘ezpolar()’ command. 

Here we explain how to use the ‘ezpolar()’ command to plot graphs of polar functions with a very basic coding example below. You can also try this in your Matlab®. 

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

>> syms x
ezpolar('1+sin(x)', [pi pi])

As you see above the use of the ‘ezpolar()’ command is very simple in Matlab®. First of all, we created a symbolic variable ‘x’ with the syms command. By using this symbolic variable, we created our polar function as a first-term inside the parenthesis of the ‘ezpolar()’ command. The second expression inside the parenthesis is the range that you want to plot the polar function.
