sudo apt-get ipython sudo apt-get install ipython ipython -pylab sudo apt-get install pylab sudo synaptic (<--used it to find pylab packages) sudo apt-get install python-matplotlib sudo apt-get install python-matplotlib-data sudo apt-get install python-matplotlib-doc ipython -pylab
And then the program works.
Actually, thanks for that, I didn't know about that stuff, and it looks really useful. If I can figure out how to get the drawings to move then it will do what I want. (to visualize the action of unitary matrices on Hilbert spaces)
But my point was that in 1982, my non-technical parents bought me a computer and then I was away. A couple of months later I had an animated model of the solar system. And I hadn't read anything except the spectrum manual (and the equivalent one for the TRS-80).
I can work out how to do the above installation for my hypothetical 12 year old son, but my poor father wouldn't have had a chance. And I suspect that the same would be true for most non-techie parents.
And how is the hypothetical son supposed to go from the pretty blue curve created by the magic plotting program to an animated solar system?
I can't see how to make the graphs move. Perhaps it can be done. Perhaps it can't and I should use SDL instead.
The point is that it is not obvious to me. Whereas the equivalent questions were obvious to a child thirty years ago.
