# lusolve

C++ port of ruby's `LUSolve` module, solves `A・x = b` for `x`, using LU decomposition.

# usage

```c++

#include "lusolve.hpp"

#include 

int main()

{

    int const kSize = 3;

    

    std::vector> a;

    a.resize(kSize);

    std::fill_n(a.begin(), kSize, std::vector(kSize));

    a[0][0] = 1;

    a[0][1] = 2;

    // setup matrix "a".

    // ...

    std::vector b;

    b.resize(kSize);

    // setup vector "b".

    // ...

    std::vector x;

    try {

        x = LUSolve::lusolve(a, b);

    } catch (std::runtime_error const&) {

        // in case singular matrix

    }

    return 0;

}

```
