Re: [Lapackpp-devel] Solving a linear system with 100 unknowns

[Dee <de...@de...>]

Hi Sivahari,

here's a small example I just have hacked:

#include <iostream>
#include <gmd.h>
#include <laslv.h>

int main()
{
    // create left side
    LaGenMatDouble A(2,2);
    A(0,0)=1.0;
    A(0,1)=2.0;
    A(1,0)=0.0;
    A(1,1)=-1.0;

    // create right side
    LaGenMatDouble B(2,1);
    B(0,0)=0.0;
    B(1,0)=1.0;

    // Solve A*X = B
    LaGenMatDouble X(2,1);
    LaLinearSolve( A, X, B );

    std::cout << A << " * " << std::endl
              << X << " = " << std::endl
              << B << std::endl;

    return 0;
}

I hope I understood your problem correctly, but I think you only need to
create A(100,100) and fill in your values.

Best regards
Dominik
