55 short videos have been created to present the
main ideas for differential equations in an active way.
Cleve Moler (who created MATLAB) developed a parallel series
of videos about numerical solutions that presents increasingly
accurate and professional codes from MATLAB's ODE Suite.

Here is the link to the Strang and Moler series on MIT OpenCoureWare.

See the MIT site for links on YouTube, iTunes and Internet Archive.

Linear algebra videos by Professor Strang are already on YouTube and OpenCourseWare ocw.mit.edu (Math 18.06 and 18.06 SC)
Here are the full links to those:
