Re: How do we create N matrices simultaneously in C++?

You don't say of what type you want the matrices to be or whether n, k, n are constant known values at the time of compile or run-time parameters - which makes a big difference.

The simplest way to create a 3 dimensional matrix is

Code:

const int n = 10;
const int k = 5;
const int N = 15;
int matrix[n][k][N];

The element of this matrix can be accessed as eg

I would like to create N matrices of dimension (n,k) simultaneously.

However, do you actually mean that you want N matrices?

Code:

const int n = 10;
const int k = 5;
const int N = 15;
typedef int mat[n][k];
mat nkN[N];

here nkN is a matrix of dimension N of type mat which is a matrix of dimensions n, k.

What are you trying to do?
