Hello,
For a few days now, I have tried a number of methods that are supposed
to provide the a(k) and b(k) coefficients for a Fourier series. These
methods are listed at the end of this post (in Java). However, not
one of these methods seems to provide the correct coefficients for the
following function;
f(x) = 2 - 2 * cos(x)

Just found Python and I love it. What an elegant language!
I would like to use it for various applications, but the
mathematical calculations are way too slow (a million sines 8 seconds
in Python vs. 2 seconds in Excel VBA), so was thinking of learning
enough C++ to do the number crunching in C++ and integrating the C++
routines with Python. My question:
My question:
Which compiler works best with Python?
I use Windows XP and 98. Have...

hi,
i've been looking all around the net (google is my friend ;-) for a
module to apply fourier transformations on images. the different ones in
numerical python and scientific python seem all to be operating on
sequences and therefore seem to be 1D fourier transform.
anyone know a library/module to do 2D image FFT in a simple manner.
or am i just too dumb to see how this is supposed to work with the 1D

Hi, I'm pretty new to using outside libraries...so I don't really understand
how to install the FFTW(fast fourier transform made at MIT) library for use
with my C++ programs. I have Windows XP and use Bloodshed Dev-C++ Version
2...if anyone could walk me through(please don't make assumptions about what I
already know other than how to write C++ code...) it would be a great help, and
I would really appreciate it.
thanks a ton

I'm porting an application from Apache Xerces to .Net and am having a couple
of small problems with deserialization. The XML that I'm reading comes from
a variety of sources, and there are two inconsistencies that Xerces is able
to handle that XmlSerializer seems not to be able to deal with.
1) Some of the boolean values that I'm dealing with are "True" and "False"
rather than "true" and "false". I'm not quite sure whether "True" and...

hey guys,can anyone tell me what is image processing,
how to do it using C.
IN KSHITIJ 2007 held at IIT kgp a que by INFOSYS is asked,
they hav given an image then cut in different orientation ,put in a
abstract(unordered) manner & asked to jumble it using C
PROGRAMMING to get the real image.

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

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...
