ok let me be more precise
I have an Z array which is the elevation
from this I extract a discrete array of Zero Crossing, and another discrete
array of Crests.
len(crest) is different than len(Xzeros). I have a threshold method to
detect my "valid" crests, and sometimes there are 2 crests between

Hi everyone
I was wondering if there is a more optimal way to write what follows:
I am studying waves, so I have an array of wave crests positions, Xcrest
and the positions of the ZeroCrossings, Xzeros.
The goal is to find between which Xzeros my xcrest are.
XXX1=XCrest
CrestZerosNeighbour=np.z

Hi Nathaniel,
Thanks for the suggestion. I more or less implemented it:
np.save('X',X);
X2=np.load('X.npy')
X2=np.asmatrix(X2)
diffy = (X != X2)
if diffy.any():
print X[diffy]
print X2[diffy]
print X[diffy][0].view(
thanks again for you response. I must still be doing something wrong!!
both options resulted in :
the TSFC_avg is: [-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
-- -- -- -- -- --
-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
-- -- -- -- -- -- -- -- -- -- -
Well, I would see solutions:
1- to keep how your code is, withj a python list (you can stack numpy
arrays if they have the same dimensions):
for filename in netCDF_list:
ncfile=netCDF4.Dataset(filename)
TSFC=ncfile.variables['T_SFC'][:]
fillvalue=ncfile.variables['T_SFC'].
I have also tried Xavier's suggestion but only end up with one value as my
average (instead of an array). I used:
for a in TSFC:
indexnonNaN=N.isfinite(a)
SliceofTotoWithoutNan=a[indexnonNaN]
print SliceofTotoWithoutNan
TSFC=SliceofTo
Thanks for responding. I have tried several ways of adding the command, one
of which is:
for i in TSFC:
if N.any(N.isnan(TSFC)):
break
else:
pass
but nothing is happening, is there some particular way I need to

Hi,
I don't know if it is the best choice, but this is what I do in my code:
for each slice:
indexnonNaN=np.isfinite(SliceOf Toto)
SliceOf TotoWithoutNan= SliceOf Toto [indexnonNaN]
and then perform all operation I want o on the last array.
i hope it does answer your question

Maybe I am asking the wrong question or could go about this another way.
I have thousands of numpy arrays to flick through, could I just identify
which arrays have NAN's and for now ignore the entire array. is there a
simple way to do this?
any feedback will be greatly appreciated.

I'm trying to do an fft on multiple columns of data at once (ultimately
feeding into a correlation calculation). I can use fft() to work on one
column:

No, people still disagree and are likely to do so for years to come with no
end in sight. That's why the preview label.

Hi all,
It's been a little over 6 months since the release of 1.6.0 and the NA
debate has quieted down, so I'd like to ask your opinion on the timing of
1.7.0. It looks to me like we have a healthy amount of bug fixes and small
improvements, plus three larger chucks of work:
- datetime
- NA
- Ben

Hi,
I mistakenly filed ticket 1973 "Can not display a masked array
containing np.NA values even if masked"
(http://projects.scipy.org/numpy/ticket/1973) against masked array
because that was where I found it. But the actual error is that the
astype function does not handle the NA object:

I'm not sure I'm crazy about leaving final decision making for a
board. A board may be a good way of carefully considering the issues,
and it could make it's own recommendation (with a sufficient
majority). But in the end I think one person needs to decide (and that
