Extract signals from the input connector and transfer them to the output connector.

The extracting scheme is given by the integer vector 'extract'. This vector specifies, which input signals are taken and in which order they are transferred to the output vector. Note, that the dimension of 'extract' has to match the number of outputs. Additionally, the dimensions of the input connector signals and the output connector signals have to be explicitly defined via the parameters 'nin' and 'nout'.

Example:

nin  = 7 "Number of inputs";
nout = 4 "Number of outputs";
extract[nout] = {6,3,3,2} "Extracting vector";

extracts four output signals (nout=4) from the seven elements of the input vector (nin=7):

output no. 1 is set equal to input no. 6
output no. 2 is set equal to input no. 3
output no. 3 is set equal to input no. 3
output no. 4 is set equal to input no. 2
