Description

This block decomposes a complex number by separating the real and imaginary parts or compose a complex number by joining the two parts. The user can select to separate or to join real and imaginary part by setting the decomposition type to 1 or 2. When it is set to 1, the input is a complex matrix and the outputs are the real and imaginary parts of the input. When it set to 2, The inputs are two real matrices, the output is a complex number with real part the first input and imaginary part the second input.

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.
