comangle()

Descripiton:

Calculate the phase angle of complex numbers.

Syntax:

A.comangle()  

Note:

External library function (See External Library Guide). Each member of the specified sequence of complex numbers returns its phase angle within the interval [-π,π].

Parameter:

A

A sequence of complex numbers

Return value:

Sequence

Example:

 

A

 

1

=[[1,2],[3,4],[5,6],[7,8],[5,0],[-5,0],[-8,-9],[-0.3,5],[3,-4],[0,0],[0,3],[0,-2]]

 

2

=A1.comangle()

3

=[1,3,5,7,5,-5,-8,-0.3,3,0,0,0]

 

4

=[2,4,6,8,0,0,-9,5,-4,0,3,-2]

 

5

=complex(A3,A4)

Generate a sequence of complex numbers.

6

=A5.comangle()

7

=[-1]

A single value is by default the real part.

8

=A7.comangle()

If elements in the sequence are non-negative real numbers, each returns 0; if they are negative real numbers, each returns π.
