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...

Hi again. I'm now asking your help because of a smal problem i'm getting
with my multiplication matrix code.
I'll try to give you as many details as possible.
My matrix structure:
typedef struct {
int col; /* number of colowns */
int lin; /* number of lines*/

Hi,
How to represent this matrix equation in C code:
/ a0 \ / 0 1 0 1 0 0 1 0 \/ b0 \
| a1 | | 0 0 1 0 1 0 0 1 || b1 |
| a2 | | 1 0 0 1 0 1 0 0 || b2 |
| a3 |=| 0 1 0 0 1 0 1 0 || b3 |
| a4 | | 0 0 1 0 0 1 0 1 || b4 |
| a5 | | 1 0 0 1 0 0 1 0 || b5 |

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...

Hi,
Is there any direct function for matrix multiplication in Python or
any of its packages? or do we have to multiply element by element?
Thank you,

Hello, I'm a newbie to C++ so excuse me if my question was trivial but
it is important to me.
I'm implementing a simple code to find the forward kinematics of a
robot:

Hi guys. I have a problem with writing the base case for the following matrix multiplication function I have implemented. Please help.
#define index(i,j,power) (((i)<<(power))+(j))
void recMultiply(int i, int j, float a, int k, int l, float b, int x, int y, float c, int s);
int i, j, k, s, matrixsize, blocksize, jj, kk, power, bsize;
float sum, maxr, total=0.0, startmult, finishmult, multtime;
float* A = NULL;
float* B = NULL;

can some one give me a hint?
I want to program the code for matrix multiplication with as less arithmetical / multiplication operations as possible.
my task is to calculate the matrix multiplication A*B*A' , where
- A' refers to the transpose of matrix A
- matrix B is symmetric matrix.
- (optional) it will be much better if the result of (A*B) or (A*B)' can be stored as temperal matrix, as
this value is required thereafter.

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,...
