complex()

Description:

Create a sequence of complex numbers.

Syntax:

complex(A,B)

Create a sequence of complex numbers using sequence A of real parts and sequence B of imaginary parts; if A and B do not have same length, automatically use 0 to fill the absent part.

complex(C)

Use sequence C of number pairs to create a sequence of complex numbers; if a member of C is a single value, take it as the real part by default and use 0 as the imaginary part.

Note:

The external library function (See External Library Guide) creates a sequence of complex numbers.

Parameter:

A

A sequence

B

A sequence

C

A second-level sequence

Return value:

A sequence

Example:

 

A

 

1

=[1,3,5]

 

2

=[2,4,6,8]

 

3

=complex(A1,A2)

Use A1’s member as the real part and A2’s as the imaginary part to create a sequence of complex numbers while using 0 at the absent place.

4

=[[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]]

 

5

=complex(A4)

Create a sequence of complex numbers using a sequence of number pairs.

6

=[1]

 

7

=complex(A6)

When member of the sequence is a single value, use it as the real part by default.
