Creating Matrix and Basic Usage

We create the matrices by passing argument as much as you want as following

#include <atrix/matrix.h>
#include <iostream>

int main() {

    // we create the matrix with dimension 5x6 
    Matrix::Matrix<double> A(5, 6);

    // we create the another matrix with dimension 2x2x3x4
    Matrix::Matrix<double> B(2, 2, 3, 4);

    // we can also create the new matrix by deep-copying  another matrix
    Matrix::Matrix<double> C(A);

    // we can assign a matrix to another matrix
    Matrix::Matrix<double> D = A;
}

We can access to the elements of the matrix as following. The elements of matrix defaultly are initialized from 0 to matrix_size - 1 respectively

#include <atrix/matrix.h>
#include <iostream>

int main() {

    // we create the matrix with dimension 5x6 
    Matrix::Matrix<double> A(5, 6);

    for (int i = 0; i < 5; i++) {
        for (int j = 0; j < 6; j++)
            // It's same as  A[i][j] 
            std::cout << A(i, j) << " ";

        std::endl;
    } 
}

Outputs Here

0 1 2 3 4 5
6 7 8 9 10 11
12 13 14 15 16 17
18 19 20 21 22 23
24 25 26 27 28 29

Now, let's change the value of A[i][j]

#include <atrix/matrix.h>
#include <iostream>

int main() {

    // we create the matrix with dimension 5x6 
    Matrix::Matrix<double> A(5, 6);

    // we change the value of A[2][2] as 100 here
    A(2, 2) = 100;

    for (int i = 0; i < 5; i++) {
        for (int j = 0; j < 6; j++)
            // It's same as  A[i][j] 
            std::cout << A(i, j) << " ";

        std::endl;
    } 
}

Output

0 1 2 3 4 5
6 7 8 9 10 11
12 100 14 15 16 17
18 19 20 21 22 23
24 25 26 27 28 29
