[Numpy-discussion] string matrices

I am trying to use NumPy to generate some matrix inputs to Maxima for
symbolic analysis. I am using a fair number of
matrix.astype('S%d'%maxlen) statements. This seems to work very well.
It also doesn't seem to pad the elements in anyway if maxlen is
bigger than I need, which is great. This may seem like a dumb
computer science question, but what is the memory/performance cost of
making maxlen bigger than I want (but making sure that it is way
bigger than I need so that the elements don't get truncated)? If my
biggest matrices will be 13x13, how long can the strings be before I
consume more than a few megs (or a few dozen megs) of memory?
Thanks,
Ryan
