### Description

MATMAGPHI Block has two types of decomposotions.
When the type is set to one, the block converts a complex number to the magnitude and the radian angle, in this case the input is complex and the outputs are real double. If the input is real double, the angle will be zero or PI and the magnitude will be equal to the absolute of the input number.
When the type is set to two, the block outputs a complex number given the magnitude and the radian angle. In this case the inputs are real double and the output is complex.

### Dialog box

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