f = Numeric.put
f(a, b, c)
put used to be in Python, but it's been in C since some release 17.x.x, I
I have a sinking feeling that I must have missed something (no interpreter
here to check it works)...
BTW, a week ago I noticed that I had reinvented the wheel in rewriting, in
an uglier and less efficient form, Numeric.allclose (hope I got the name
right). As far as I can see, it isn't listed in the manual. Did I miss
it? All it would need is the docstring copying over.
