Hi all,
I am writing a template matrix class in which the template parameters are
the number of rows and number of columns. There are a number of reasons
why this is an appropriate tradeoff for my particular application. One of the
advantages is that the _compiler_ can force inner matrix dimensions used in
multiplication to agree. A _complie-time_ error will be triggered if you
write A * B and the number of coluns in A does not equal the...

Hello. I am trying to learn how operator overloading works so I wrote
a simple class to help me practice. I understand the basic opertoar
overload like + - / *, but when I try to overload more complex
operator, I get stuck.
Here's a brief description what I want to do. I want to simulate a
matrix (2D array) from a 1D array. so what I have so far is something
like this:

Hi Guys,
I have a matrix multiplication program in C that multiplies two
matrices.
When their size is 3*3 or 800*800, the program runs fine. But above
that size, I get a "segmentation fault".
I need this huge size as part of my assignment.

Hi ,
Recently I have been commited to the task of "translating" some complex
statistical algorithms from Matlab to C++. The goal is to be three
times as fast as matlab ( the latest) .
I've used various techniques ( loop unrolling, loop jamming...) and
tried some matrix libraries : newmat (slow for large matrix) , STL
(fast but ..not usefull) , hand coding (brain consuming...), and
recently Meschach...

Below is a module (matrix.py) with a class to implement some basic
matrix operations on a 2D list. Some things puzzle me about the best
way to do this (please don't refer to scipy, numpy and numeric because
this is a personal programming exercise for me in creating an
operational class in pure python for some *basic* matrix operations).
1. Please take a look at the __init__ function and comment on the
initialization of the list data...

Hello everyone. I'm writing a program which uses a class called matrix. I have written all of the different functions, constructor, etc.
When I run the program I receive "Constructor", which I placed in the constructor, and then the program crashes. I have no clue where my problem is.
The matrix is for size 2x2 up to 10x10, and it must be square.
Below is the code:
#include <iostream>

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...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

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...
