Requires: MathScript RT Module
c = is_real(a)
Determines whether a matrix is real. A number is real if and only if in a=Re(a)+Im(a)*i, the second term Im(a) is 0. A matrix is real if and only if all elements in that matrix are real.
|a||Specifies a scalar, vector, or matrix of any data type but plot objects and (Control Design and Simulation Module) state-space, transfer function, and zero-pole-gain models.|
|c||Returns 1 if a is a real matrix. Otherwise, this function returns 0. c is a Boolean.|
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|
