The Extract Signal component extracts signals from the input, ; rearranges them; and then transfers them to the output, y.
The extracting scheme is given by the integer vector, . This vector specifies which input signals are taken and the order in which they are transferred to the output vector. Note, that the dimension of has to be equal to the dimension of the output. Additionally, the dimensions of the input connector signals and the output connector signals have to be explicitly defined in and .
