[Numpy-discussion] A bit of advice?
Thu Jun 23 07:02:24 CDT 2011
I have a set of experiments that I want to plot. There will be many plots.
Each will show different test conditions.
Suppose I put each of the test conditions and results into a recarray. The
recarray could be:
arr = np.empty ((#experiments,), dtype=[('x0',int), ('x1',int), ('y0',int)]
where x0,x1 are 2 test conditions, and y0 is a result.
First I want to group the plots such according to the test conditions. So, I
want to first find what all the combinations of test conditions are.
Dunno if there is anything simpler than:
cases = tuple (set ((e['x0'], e['x1'])) for e in arr)
Next, need to select all those experiments which match each of these cases. Now
I know of no easy way.
Any suggestions? Perhaps I should look again at pytables?
