Help with lti lib on LyME (Palm OS 5)

[Francisco Bonillo]

Hi, I'm trying to configure a script using the lti library, but i have
some troubles with this library.

First i do it's to load the lit and control lib:
> use lti
> use control

then i define a tf object:
> sys = tf(1,[1 2 3])

after that i try to calculate de step response function
> step(sys)

but it returns
Undefined function 'step'
(lti/tf::step;1287)

then trying with some other functions for tf objects, i had found that
only works until 'margin' function.

When i try to edit lti lib, it give me an error
cannot get record (err527)

It seems to be a problem because the file its too large. There is a
way to split it by example in ss lib, tf lib, etc.? in the way to make
Palm OS capable to use this excelents functions.

thanks

Try the following command:

> step(1, [1, 2, 3])

See reference: step(numc, denc)

Best regards.
