Description

The Real-Imag to Complex block converts real and/or imaginary inputs to a complex-valued output signal. The inputs must be real-valued signals of type double. The data type of the complex output signal is double.

The inputs may be both vectors of equal size, or one input may be a vector and the other a scalar. If the block has a vector input, the output is a vector of complex signals. The elements of a real input vector are mapped to real parts of the corresponding complex output elements. An imaginary input vector is similarly mapped to the imaginary parts of the complex output signals. If one input is a scalar, it is mapped to the corresponding component (real or imaginary) of all the complex output signals.

Parameters and Dialog Box

Input
Specifies the kind of input: a real input, an imaginary input, or both.
Real (Imag) part
If the input is a real-part signal, this parameter specifies the constant imaginary part of the output signal. If the input is the imaginary part, this parameter specifies the constant real part of the output signal. Note that the title of this field changes to reflect its usage.

 Yes
Sample Time
