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

From: Sivahari N. <siv...@gm...> - 2014-02-28 08:45:16

Hai all,

I am new to lapackpp. I want to do a curve fitting module ad part of my
academic project. I want to solve a linear equation system having 100
different linear equations each with 100 unknowns. Can any one provide some
sample code or documentation link for this.

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

hai Dominik,

It worked well, thank you.  Is there any class in lapackpp deals with curve
fitting?

Hello Sivahari,

not that I'm aware of. I have programmed it manually in my Ph.D. thesis
with the help of lapackpp. That means I got my input parameters, created
a Least-Square matrix, solved it and extract the values for my
line/polynom/spline (the latter in my case).

Best regards
Dominik
