Question: I'm a student who has to extract transfer functions from block diagrams quite often. It would help if there was a graphical tool where I could manipulate block diagrams and see their resulting transfer function. Does this exist? I tried Googling for "Block Diagram Solver" and "Block Diagram to Transfer Function", but I didn't find anything. If this does not exist, I will go the programmers stack exchange to find out the algorithmic reason that this is impossible to accomplish in software.
Why I thought I could ask this question here: In the FAQ, it mentions that I can ask about software that mathematicians use. I thought this would pertain to that.
