I was recently looking through upcoming Coursera offerings and came across the course Coding the Matrix: Linear Algebra through Computer Science Applications taught by Philip Klein from Brown University. This looks like a fine course; but why use Python to teach linear algebra? I suppose this is a blind spot of mine: MATLAB I can see. That software has a long tradition of being used in applied mathematics and engineering applications. The Linear Algebra course from MIT open courseware is based on MATLAB and half the linear algebra books published by SIAM use MATLAB.
