Hello,

I am new to mathdotnet but I would like to learn how to setup sparsematrix and solve laplace equation Lx = b.

Before I was using Eigen library in C++

And the syntax looked like this for solving equation Lx = B: - x is unknown

```
Eigen::SparseMatrix<double> L(n, n); // nonzero elements of L as triplets: (row, column, value)
Eigen::MatrixXd rhs(Eigen::MatrixXd::Zero(n, 1)); //B matrix
```

Then I setup L matrix from triplets

`std::vector< Eigen::Triplet<double> > triplets_L;`

build sparse matrix from triplets

`L.setFromTriplets(triplets_L.begin(), triplets_L.end());`

and solve matrix

```
Eigen::SparseLU< Eigen::SparseMatrix<double> > solver(L);
Eigen::MatrixXd x = solver.solve(rhs);
```

So the final result I seek is X matrix is there similar workflow in math dot net?

Or can someone point me to how to setup Ax = B equation for solving sparse matrix?
