Hi all,
I try to use recarray with rec.fromrecords on time-series, datas come from a
file where they are stored in csv format, with after each data colum there is
one column meanning the state of the data, and the first column is for dates.
Then, is it possible to directly transform column of str
Dear Friends,my question is the following:Suppose i have the following code:>>> from LinearAlgebra import *>>> from Numeric import *>>> A = [1,2,1,3,1,3,4,1,2]>>> B = reshape(A,(3,3))>>> C = sum(B,1)>>> Carray([4, 7, 7])>>> Now, my problem is to construct a degree matrix D which is a 3 * 3 matrix w
Hi,
[SU]: Now, my problem is to construct a degree matrix D which is a 3 * 3
matrix with diagonal elements 4,7,7
You might have a look at the Numpy Example List, at the function diag().
Ciao,

Hi list,
I'm using PyArray_DescrConverter with a dict object to create a "struct-like"
dtype from C.
As the struct contains different data types I run into "unaligned access"
problems.
Is there a way to force alignment or to get trailing unused bytes in the
dtpye?
Thanks, Martin

No reaction up to now, so...

I haven't tried VisIT before but thanks for the link. I also downloaded and am
checking it out.
Along this same line of discussion, has anyone tried OOF2 which is an FEA
package that also has some strong python connections?

Hi,
I am facing a rather frustrating problem with numpy/scipy: after
upgrading to svn numpy and scipy, and trying to remove most of the now
unnecessary casting (floats) the program I wrote does not give me the
right answer. It seems that the answer is somewhat scaled down (but not
in a simple way)

(get recent SVN as there were some bugs just fixed.

I have looked at it, and I even know somebody who is using python to
put in a data reader for FVCOM (a finite volume ocean model). He has
a prototype working. I have no experience with the python bindings
personally.
I looked into compiling it from source (for an intel mac), but it was
