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.

+ **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.
