MIMO Transfer Function #557
Description
Let's say I have a MIMO system where the numerator is
NUMv = [[1], [2]]
and the denomenator
DENv = [[1, 2], [3, 4]]
and I try to make a transfer function by
Hv = tf(NUMv, DENv)
This is how I would set it up according to how I've understood the docs.
However, I get this error message:
"TypeError: The numerator and denominator inputs must be scalars or vectors (for SISO), or lists of lists of vectors (for SISO or MIMO)."
What am I missing? What triggers the TypeError? I've tried setting it up the same way in Matlab, which was successful, but I need it to work in Python as well.
Thanks in advance!

Nest them one more pair of
[]to make it list of lists as if your are doing a 3d array. Currently you are trying to buildSo you need

@ilayn beat me to it, but here is a bit more detail.
As you have it written, the meaning is ambiguous: are you trying to create a 2-input, 1-output system or a 1-input, 2-output system?
For 2-input, 1-output, use
For 1-input, 2-output, use

Thank you!
I was trying to create a 2-input 1-output system.
You solution worked like a charm!
