Talking about that, what happened to these projects o
A key thing to remember here is that each user has their particular set
of "small things" that are all they need from scipy -- put us all
together, and you have SciPy -- that's what it is for.

A big part of the issue is that getting many of those pdfs into NumPy

for matrices you should now use m.diagonal() I think. So diag doesn't
qualify.

I have the following two lines in a for loop:
if len(idx):
x[idx,i] = x[idx,i-1]
where idx is the output of a where statement.
I need the 'if len(idx)' line to prevent an error when idx is empty.
Would it make sense to allow
x[idx,i] = x[idx,i-1]
when idx is empty instead of raising an er

Thanks for all the input so far. The only thing that seems odd about
the omission of probability or quantile functions in NumPy is that all
the random number generators are present in RandomArray. At any rate,
hopefully this bit of functionality will be present in the future, but
for now, IMO the
