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;
>> 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®;
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.
