> I saw 2 more problems with the step function. Please try the 2 following
test cases.

> I append a file in which I implemented a workaround. Maybe this can help you
making the final correction.
Thanks for the report and the workaround. I will have a look at this.

> Finally I guess that the new argument "names" is not compatible with the old
step function (and other functions calling __time_response__.m).
> Could you also provide these functions?
Ah yes, the new "names" argument was introduced for fixing an issue with the
legend. You can download the files which are calling __time_response__.m
(step.m, ramp.m, impulse.m, initial.m) from the same location, just replace
the file name in the url.
