@miroslavfikar It would be great to add a unit test the triggers the error (prior to your fix).

Coverage decreased (-0.002%) to 92.721% when pulling 9bd61b0 on miroslavfikar:mifi_ufun into 2ce4bbd on python-control:master.

I updated the fix to use extrapolation, since this is what is supposed to happen. The example now runs without throwing and error. (I couldn't figure out how to create a simple unit test since it seem to depend on the integrator asking to sample outside of the time range.)

@miroslavfikar It would be useful if you can confirm that the new version gives a correct result for your example.

@murrayrm Yes, I confirm, I get the correct results with your commit, thanks.
