Complex numbers are just another more general data type which MATLAB
®
can handle. Thus in MATLAB
®
there are arrays, vectors, matrices and functions of
complex numbers, and the user may use those almost as she/he is accustomed
to with real numbers. Any complex number can alternatively be characterized by an
absolute value
r ¼
p
x
2
þ y

and an angle
y
:
¼ re
iy
z
(15.11)
The corresponding MATLAB
command are:

The output for the angle lies between -
p
and
p
.
