Description
~~~~~~~~~~~

This block computes the magnitude and the angle of a matrix of complex
numbers or composes a matrix of complex numbers from a matrix of
magnitudes and a matrix of angles with respect to the value of
**decomposition type** parameter. The following table summarize the
bloc behaviour :


**Decomposition type** **Inputs** **Outputs** **Operation** **1** One
(complex or double) Two (double) Conversion complex to magnitude
(first output) and radian angle (second output). If the input is
double, the angle will be zero or PI and the magnitude will be equal
to the absolute of the input number. **2** Two (double) One (complex)
The block outputs a matrix of complex numbers built with the magnitude
and the radian angle inputs coming respectively from the first and
from the second inputs.




Dialog box

+ **decomposition type (1=Complex2MAG&PHI 2=MAG&PHI2Complex)**
  It indicates the rule of the conversion. Properties : Type 'vec' of
  size 1.
