I'm trying to do some georeferencing - using points of known
location (ground control points, GCPs) on an image to develop
a polynomial that can be used to approximate the locations of
other points.
I usually use the Python bindings to GDAL
http://www.remotesensing.org/gdal/
to manipulate geospatial data but there are no Python bindings
for GDALCreateGCPTransformer()....

Hi all,
Has someone written a C binding to transfer matrices from C to Python
and vice versa ?
Any pointer would be appreciated.

Hello.
I am looking for advice on what is "best practice" regarding looping
through a form to check its checkboxes and associated data fields.
Here is what I am trying to do (Here is the page I am working on:
http://www3.telus.net/thothworks/LinLeastSqPoly4.html).
I provide a form for a user to enter up to twenty (M = 20) data pairs.
The user need not enter data for all twenty pairs, but
the user must indicate that data is present by...

Is there any sparse matrix package compatible with Numeric/Numarray ? Ideally, the implementation of
a matrix (dense/sparse) should be transparent to the application. However the APIs of the only
packages I'm aware of -- the Sparse module in Scipy and PySparse --are both pretty incomplete
compared to (dense) numeric arrays. Any alternatives ?

Hello People
I hope I am On Topic. Anyways, here is my problem. Any insights would
be really appreciated.
I have wrapped a C IO module using SWIG -> Python Module. Suppose the
name of the module is "imageio" and the reader function from the file
is image_read() which returns an object ( "filled" C structure) with a
lot of members.

Hello,
I'm planning to use Python in order to teach a DSA (data structures
and algorithms) course in an academic institute. If you could help out
with the following questions, I'd sure appreciate it:
1. What exactly is a Python list? If one writes a, then is the
complexity Theta(n)? If this is O(1), then why was the name "list"
chosen? If this is indeed Theta(n), then what alternative should be
used? (array does not seem suited for...

Python matrices are usually defined with numpy scipy array or similar.
e.g.
I would like to have easier way of defining matrices,
for example:
Any ideas how could this be done? The ";" sign is reserved, the ""
is used for lists.

So what i need is this; (I'm very new at this,, programming in C I
mean...)
In matlab I had a while loop, and after each loop was done I added my
resulting matrix to an object. Seeing the loop is conditional to my
results I do not know in advance how many loops I need. The matrices
are Nx * Ny* Nz*6.
In C I put my matrices into 1D arrays. So I thought that if I use a
counter for each time i do a loop and the calloc and realloc function

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,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
