- Expressions Of Complex Numbers In MatLab®(Illustrated Expression)

Complex numbers are frequently used in mathematical phenomenons in calculations. So Matlab® has expression standards for the complex number. In this article we will explain;

- How to use complex numbers in Matlab®?
- What are the complex numbers’ commands in Matlab®?

```
>> a = 6+8i
b=abs(a)
c=real(a)
d=imag(a)
f=angle(a)
a =
6.0000 + 8.0000i
b =
10
c =
6
d =
8
f =
0.9273
>>
```

As you can see above, the expression of complex numbers in Matlab® is very basic. You need to type the complex number as shown above in Matlab®. The imaginary value is typed as ‘i’ as you see.

There are a bunch of functions about complex numbers in Matlab®;

**abs():**This command indexes the absolute value of the complex number that typed inside it as shown by green arrows above.**real():**This command indexes the real side of a complex number that typed inside this command as shown in Matlab®.**imag():**You can index the imaginary side of a complex number in Matlab® by typing the complex number inside it as shown above.**angle():**You know that every complex number can be displayed in the cylindrical coordinate system. In a cylindrical coordinate system, every point has a place and angle values. With this command, you can index the angle value of a complex number in cylindrical coordinates in Matlab® as shown above.**conj():**Indexing the conjugate value of a complex number that typed inside this command in Matlab®.

As you know that you can use the indexed values in other calculations or codes in Matlab®, you can also use these indexed complex number values in further calculations or codes in Matlab®.

The general logic about complex numbers in Matlab® can be stated basically like that. If you wish much more complex example about complex numbers and their functions in Matlab®, we can publish one.
