Hi there
I wrote a short program which reads scientific data from
a file and stores its values in a Numeric array.
At the same time it reads the names of its dimensions which
are then in the same order as the indices of the Numeric
array.
After then I want to access the data in the array by its name
the way that I keep all indices at constant values except the

Hi,
I have a tricky problem with Numeric. Some time ago, I have generated
a huge and complex data structure, and stored it using the cPickle
module. Now I want to evaluate it quickly again on a workstation
cluster with 64-Bit Opteron CPUs - I have no more than three days to
do this. Compiling Python and running Numeric has been no problem at
all. However, I get an error message when accessing the data pickled
before. (I can load it...

I am just starting to use python, and as such my question may well be a
bit simplistic. I am currently trying to write what should be a very
basic set of routines for reading and writing to a binary grid format
(ERMapper). However:
I am struggling to find the correct tools to write a row of a
2-dimensional array to a binary file. In matlab the command looks
like:
fid=fopen(filename,'wb');

Using Access 97, Windows XP
I'm receiving a Numeric Field Overflow error during text import that I
did not receive before I split my database. Another thread I found
suggested that the cause of this error might be due to columns on the
text file being in a different order than fields in the destination
table, but they're the same in my case.
I'm thinking a workaround might be to import to a temp table in the
front-end, run an append...

Hi,
I have the following loop that I think can be written to run faster in
Numeric. I am currently using Numeric.
range_va =
main.xsize= 600
main.ysize= 600
#msgva is an (600x600) Numeric array with mutiple occurrences of the
values in range_va
#sat_id is an (600x600) Numeric array with values ranging from -2 to 2

Hi,
I am posting here to seek for help on type conversion between Python (Numeric Python) and C.
Attachment A is a math function written in C, which is called by a Python program. I had studied SWIG and Python/C API a bit. I was able to pass numeric array (Numeric Python) into the C function and access/change these arrays.
Problem I am having is that I couldn't quite get the array converted back to some PyObject or something that...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
