how to import the pywt library which is a python library in dev c ++?

Question

I'm trying to run this code which was picked up by someone I can't reach anymore, the code calculates the dwt2 and idwt2 of a square matrix

#include <iostream>
#include <pywt>
#include <numpy>

using namespace std;

int main() {
int Matrix=numpy.array([[1.0,2.0,3.0,4.0,],[5.0,6.0,7.0,8.0,],[9.0,10.0,11.0,12.0,],[13.0,14.0,15.0,16.0,],])

cout << "-----------------------------------------------------------------";

cout << "Matrix : \n";

cout << Matrix[0];

int A,(B,C,D)=pywt.dwt2(Matrix,'haar', mode='symmetric')

cout << "-----------------------------------------------------------------";
cout << "A : \n";
cout << A[0];
cout << "-----------------------------------------------------------------";
cout << "B : \n";
cout << B[0];
cout << "-----------------------------------------------------------------";
cout << "C : \n";
cout << C[0];
cout << "-----------------------------------------------------------------";
cout << "D : \n";
cout << D[0];

int newMatrix=pywt.idwt2((A,(B,C,D)),'haar',mode='symmetric')

cout << "-----------------------------------------------------------------";
cout << "newMatrix : \n";
cout << newMatrix;

return 0;
}

and he said that these libraries use for both python and c++, and I just have to put them in the same folder as C ++ code, but I am new to C++ and I have tried many ways to make it work and to include libraries in C:\Program Files (x86)\Dev-Cpp\MinGW64 but I still get the same error, [Error] pywt: No such file or directory, I can't import the libraries and make the code work, can you help me please.

Thank you so much.

I saw that you are using MinGW64, therefore I think you are using CodeBlocks IDE. To add a library in CodeBlocks, go to Settings->Compiler->Global compiler settings-> Search Directories-> and add the include directory from the downloaded folder. Then, do to Linker settings and then add the libraries you need.

You can read an useful article here !

By the way, you can do that using just c++. I think that is more easier to do. That's the code:

#include <iostream>

using namespace std;

int main()
{
    //this is the declared matrix
    float matrix[4][4]={{1.0,2.0,3.0,4.0},{5.0,6.0,7.0,8.0},{9.0,10.0,11.0,12.0},{13.0,14.0,15.0,16.0}};

    //this is the equivalent of the following line from your code
    //cout << "----------------------------------------------------";
    //I used a for loop to print 65 - characters
     for(int i=0;i<65;i++)cout<<'-';

    cout<<"\nMatrix:\n";

    //That's how basically we print a matrix, using 2 for loops
    //one for each row, and one for each column
    for(int i=0;i<4;i++)
    {
        for(int j=0;j<4;j++)cout<<matrix[i][j]<<' ';

        cout<<'\n';

        for(int i=0;i<65;i++)cout<<'-';

        cout<<'\n';
    }

}

That's an image with the result: result
