This is my transfer function:
H1s =
1.25e04 s
----------------------
s^2 + 1.25e04 s + 1e10
Continuous-time transfer function.
(output from the MATLAB console)
When I try to do bodeplot(H1s) I get the error "Error using DynamicSystem/bodeplot (line 108) Too many input arguments."
Why is this? When I used bodeplot on a transfer function previously, it worked just fine.

With your advice I found out I had a file called "line.m" which superceded the function used by bode and several other functions. Thanks for the help.

Ah! That would do it.
Which toolbox had its own line.m ? line() is used by plot() so I would have expected a lot of plotting trouble.
