Re: error "can't perform indexing operations for <unknown type> type"

[cmire]

Thank you so much!  The output matches the example in the text perfectly 
(Applied Quantum Mechanics, by A. F. J. Levi -- Chapter 3, example 3.7).  Now 
I can rework this code for my homework (different shapes for the quantum 
wells -- so I have to modify the calculations for potential).

In the future, I'll remember to add code as an attachment.  I've never used 
Matlab, Octave, or Scilab before (have used ROOT for monte carlo 
simulations), and I am very impressed with the GPL scientific programs (and 
happy to have them as alternatives).

Again -- thanks!
Best Regards,
Charles Mire
