Owning Class: basic
Requires: MathScript RT Module
c = sign(a)
Returns the sign of the input elements.
|a||Specifies a real or complex scalar, vector, or matrix.|
|c||Returns the sign of the elements in a. c is a scalar, vector, or matrix of the same size as a and, for real a, can return the following values: +1, 0, or -1. The sign of 0 is 0.|
For nonzero complex numbers, this function returns a complex value with the same phase as the input and with a magnitude of 1.
The following table lists the support characteristics of this function.
|Supported in the LabVIEW Run-Time Engine||Yes|
|Supported on RT targets||Yes|
|Suitable for bounded execution times on RT||Yes|
C = sign([0, 2, -3])
