Extract signal components
"Extract" operates on complex and multi-channel signals and returns another multi-channel signal consisting of the selected components (or channels) extracted.
Parameters of "Extract" are
- i, which is the dimension index or channel of the first component to be extracted and
- j, which is the dimension index or channel of the last component to be extracted.
Index counting starts at 1 here.
y = Extract(x,i,j);
