I think I could use that to write a function savematrix(filename, a, b,
c,...)
Is there a way to write a loadmatrix(filename) that doesn't return
anything but makes the matrices a, b, c, ... available?
I think there is, that is why I mentioned the saving the environment
thingee. IIRC, I saw code for something like that a couple of years back but
I don't recall the details. Maybe something like:
In [80]: globals()['x'] = [1,2]
In [81]: x
Out[81]: [1, 2]
Then you just have to merge the pickled dictionary with globals(). Like
this:
globals().update(mystuff)
where mystuff is the dictionary where you have your stuff. This could
probably also go something like
globals().update(load(f))
where f contains the pickled dictionary.
