Syntax

Im(x)

x
is a number, vector, or matrix

Description

If
x
is a number,Im(x)
is the imaginary part ofx
. 
If
v
is a vector,Im(v)
is the vector of the imaginary parts ofv
. 
If
A
is a matrix,Im(A)
is the matrix of the imaginary parts ofA
.
Typewise, Im(x)
is always a real number, vector, or matrix.
Examples
