csgn
returns the sign of a vector of real of complex values
Syntax
s = csgn(z)
Arguments
- z
a vector of values on which we want to compute the sign
- s
if the real part is not equal to zero:
+1
if the real part of an element is positive-1
if the real part of an element is negative
If the real part is equal to zero:
+1
if the imaginary part of an element is positive-1
if the imaginary part of an element is negative
if the element is equal to zero, then returns
%nan
Description
The csgn
function returns the sign of a vector of real of complex values z
.
Examples
A = [1 1+%i 0 -1 1-%i -1-%i]; csgn(A)
