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. |
