Well for this particular example you could do
a=array([len(b)-sum(b), sum(b)])
Since you are just counting the ones and zeros.

This next one is a little closer for the case when c is not just a bunch of
1's but you still have to know how the highest number in b.
a=array([sum(c[b==0]),  sum(c[b==1]), ... sum(c[b==N]) ] )

So it sort of depends on your ultimate goal.

Re: [Numpy-discussion] can this be made faster?

[Bill B. <wb...@gm...>]

Yeh, I spoke too soon.  Tried a little example and it seemed to work.
I don't get a traceback here, but your example doesn't work as expected, either.
I get [1,1] as the answer with numpy 1.0rc1.  Probably it should be an
exception, though.

It seems to work if len(b)<=len(a)  and when no indices are repeated in b.

[Daniel M. <dm...@gm...>]

Is there a 'loop free' way to do this in Numeric

for i in arange(l):
   a[b[i]]+=c[i]

where l == len(b) == len(c)

Thanks for the reply Travis.

I have a custom Date class which allows creation of different frequency Dat=
es (annual, monthly, etc..). Two dates of the same frequency can be subtrac=
ted, and integers can be added to a Date, with the obvious results in each =
case.  I store these dates in arrays currently using the "object" dtype.
=20
However, the problem with this is that I can't tell the frequency of the Da=
tes in the array without inspecting invidual elements of the array, or subc=
lassing the array object itself. I'd like to be able to have each frequency=
 of date as a data type  (DateAnnual, DateMonthly, etc...). It just seems l=
ike a cleaner approach to have these dates defined as data types.
=20
I would be open to the idea of defining this in C, but I don't really have =
any examples to work with for that either.
Many thanks for any advice/suggestions you can provide.

It might be possible if you have a Windows build of PyGTK, but not with the gvim 
integration. However, pida also supports other PyGTK-accessible editor widgets. 
See its documentation for details.

A "true" user-defined data-type can only be done in C.

However.  You can use the "VOID" data-type to create a type with 
multiple fields.   What do you want to do with your user-defined data-type.

If you are using Debian stable (sarge), you might need to read

http://www.its.caltech.edu/~astraw/coding.html#libc-patched-for-debian-sarge-to-fix-floating-point-exceptions-on-sse2

In short, libc in Debian stable has a bug that makes programs crash with
SIGFPE when SSE instructions are invoked. The solution is to recompile
libc from patched sources, and replace libm.so.6. At least for me this
fixed crashes in numpy.

OK... I am so angry at myself... I spent around 2 hours fiddling around with 
blas/lapack and numpy, and the problem was that I wasn't removing the 'build' 
directory between compiilations. Apparently it's not enough to run "setup.py 
clean" (I read this and forgot about it) to recompile lapack_lite.so. Now 
numpy imports fine and everything I use it for works as before (only a bit 
faster).

Karol

P.S.
I still get a floating point exception when running the numpy tests, though. I 
haven't checked out numpy for some time, so I don't now if it's a bug, or if 
it's my setup. The same thing happens when I use my manually built 
atlas/lapack and the built-in debian atlas/lapack libraries. I'd be grateful 
for a comment on if this is just me:

[Numpy-discussion] paypal won't take my money for scipy docs

[Greg S. <gs...@al...>]

I fill in the credit-card form, press continue, and it comes back with 
   "Some required information is missing"; the indicated missing info is 
the 'security code' you copy in to prove you are human, which I had 
entered. This happened 3 times in a row, and I am certain I got it right 
at least the last two (I even listened to the audio read-out the third 
time). So I am starting to get concerned that something is being 
intercepted..

I'm guessing that a paypal merchant is more likely to get attention from 
paypal than an accountless purchaser - any idea what's going on here?

xerbla is an error handler for the LAPACK routines. Make sure you included
xerbla.f when building your LAPACK library. Check the symbols included in
the library with strings or objdump.

Hope this helps.

[Numpy-discussion] Numpy types and object comparison

[Matthew B. <mat...@gm...>]

Hi,

I am sorry, I am still struggling with object arrays - and here -
numpy data types.  Is there any easy way to explain why comparisons
with numpy types give a different output from comparisons with
non-numpy types:

In [108]:oa = zeros((1,), dtype=object)

In [109]:oa == int
Out[109]:array([False], dtype=bool)

In [110]:oa == int32
Out[110]:False

Many thanks for your patience,

Matthew

[Numpy-discussion] problem with lapack_lite / BLAS

[Karol L. <kar...@kn...>]

Dear list,

 I'm trying to compile ATLAS 3.6.0 and LAPACK 3.0 (+ update) and use them with 
the latest numpy (checked out today). Installation seems to be fine, all the 
libraries are detected. When I import numpy, however, I get this:

Python 2.5 (r25:51908, Sep 27 2006, 17:40:29)

Does anyone know where this comes from?

Cheers,
Karol

Pida looks nice, thanks for the pointer. Unfortunately, the mercurial
support needs editing to make it work at a basic level. To make pida really
work right for distributed repositories looks trickier because distributed
version control doesn't necessarily have a central repository while the
current pida interface looks to be based around that concept.

Thanks for reminding us again. 

I don't think this is too bad of a deal.  I propose to move repmat(A, 
M,N) to matlib.py and replace it in numpy with a function named

tile(a, reps)

That is more general-purpose.   If this is not acceptable, please speak up.
