In the snippet below, if the problem line is present, my program
crashes during the Matrix operator*(const Matrix&) call. Would
someone point out to me why I'm having this problem?

Hello,
I need to implement a library containing a hierarchy of classes
together with some binary operations on objects. To fix attention,
let me assume that it is a hierarchy of algebraic matrices with the
addition operation. Thus, I want to have a virtual base class
class Matr;

I have a problem to copy (assign) a matrix to another matrix. Curreny, I
know copy the number using loops, while it will take some time, I wonder if
there have faster method. The following code explain my situation detailed.
double ** matrixa, **matrixb;
int nrow = 10, mcol = 10;
matrixa = initmatrix(nrow, mcol); // allocate memory a
matrixb = initmatrix(nrow, mcol); // allocate memory b
// copy a => b
for (int i=0;i<nrow;i++)

Hello Experts!!
I have two small classes called Intvektor and Matris shown below and a main.
Class Intvektor will create a one dimension array of integer by allocate
memory dynamically as you can see in the constructor.
Class Matris should create a matris by using class Intvektor.
So what I want to have is a pointer to an array of Intvektor and in each
positionindex in this array will I have a pointer to an array of Intvektor
in this...

Hi i have a small(?) problem and i hope you can help me.
i have a basis class "Matrix" that contains a 2d matrix.
you can fill the matrix by a method called "setData(int x,int y)".
two child classes "MatrixTypeA" and "MatrixTypeB´" inherit the matrix
and the filling method. ok.
both childs have different attributes and variables but happen to use
the same matrix type to store the data.
now theres a class "MatrixGenerator" that fills...

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...

Hi all,
I'm trying to implement a certain class but I have problems regarding
the copy ctor. I'll try to explain this as good as possible and show
what I tried thusfar. Because it's not about a certain code syntax but
more a 'code architecture' thing , I'll use simple example classes
(which are certainly not complete or working...) just to illustrate the
idea (and I may make some mistakes because I'm not that experienced...).

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,...
