MATZREIM
Complex decomposition/composition
Block Screenshot
Contents
Description
This block decomposes a matrix of complex numbers by separating the real and imaginary parts or composes a matrix of complex numbers by joining the two parts with respect to the value of decomposition type parameter. The following table summarize the bloc behaviour :
| Decomposition type | Inputs | Outputs | Operation |
| 1 | One (complex) | Two (double) | Decomposition: The real part and the imaginary part of the input are available respectively on the first and the second outputs. |
| 2 | Two (double) | One (complex) | Composition: The output is a matrix of complex numbers built with the real and imaginary parts coming respectively from the first and from the second inputs. |
Parameters
Decomposition type (1=Complex2Real&Imag 2=Real&Imag2Complex)
Indicates the type to use for the decomposition. See the description part for more information.
