Robert,

  That's where I went off. I forgot that I'm still dealing with a 1D NumPy
array and not a list. No wonder I had such fits!

  I have not seen the 'j' suffix before. That was throwing me.

  That's so much easier than what I ended up doing, which was creating
another variable and assigning to that an explicit cast to real of the
array.

  Now that's really nice!

Thank you very much for today's lessons. I really appreciate them
