[Octave-bug-tracker] [bug #65401] [octave forge] (control) A problem with lsim command

[Ahmed Salah Hammad Ahmed]

Follow-up Comment #4, bug #65401 (group octave):


[comment #2 comment #2:]

(3x1001)


> The documentation for lsim (also on Matlab) says that u must have length(t)
rows and as many columns as there are inputs. It looks like Matlab is just
more "tolerant" regarding the shape of u. I can add this "robustness" to
Octave's control package, too.

code as suggested by Nicholas in comment #2.


Indeed, transposing the input matrix worked, so I just need input matrix to
have no. of columns as no. of inputs, and no. of rows as the time vector,
right?
For the second error, I have posted the lines of code in the previous comment
if you want to check it out


Thanks a lot
