Lecture 3 | Introduction to Linear Dynamical Systems

[essaied66]

For the guy asking about why [-1 -1 -1 -1 -1 1 1 1 1 1 ] is not in the null space, because it has shifted the mass to the left by 5 meters let us say although at the end it has a zero velocity. The idea of the null space associated with the Force example is that we apply a set of forces but the net or the final result is the mass is back to the original position with zero velocity. I hope this helps!

time 1:04 he is refering to ebonic linear algebra.

I can't understand that how [-1 1 -1 1 0 0 0 0 0 0] is in null space and why is

[-1-1-1-1-1 1 1 1 1 1] not in null space. Plz do reply.

Too bad that to see the solutions to the exercises on his site, you do need a stanford account.

Practical use coming together with the theory in behind, this is really good. Thanks for Stanford.

Prof. Boyd coming with a sample of practical use matching to any theory in behind which is very useful for understanding. Thanks Stanford for this fruitful course.

tank you standford!!!

Engineering is based on linear systems, thats why I highly recommend go thru this course, also to do some exercises in order to digest and interiorize the material. But the most important thing is to really understand the semantics within each equation, since you are going to be embedding all these stuff in software.

These are truly remarkable lectures. Obviously I'm only on the 3rd one but I'm excited to go through the whole course.

It's nice to watch before bed and think about while falling asleep.

Thanks Stanford for posting this.  I find it disturbing there were no comments so I had to add.
