MATZREIM
Complex decomposition/composition
Block Screenshot
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.
Dialog box
- decomposition type (1=Complex2Real&Imag
2=Real&Imag2Complex) Indicates the type to use for the
decomposition. See the description part for more information.
Properties : Type ‘vec’ of size 1.
