This is the example for LU. What could be wrong ?
var maxVertexIndex = vertices.Keys.Max(i => i);
var L = new SparseMatrix(maxVertexIndex, maxVertexIndex);
//(fill L, code omitted)
var rhs = MathNet.Numerics.LinearAlgebra.Vector<float>.Build.SparseOfIndexed(maxVertexIndex, vertices.Values.Select(v => (v.Index, v.Position3d)));
var result = solver.Solve(rhs); //Crash here

I had a crash in SVD too 9 months ago. I have rewritten the SVD alg from scratch and it works as expected. So am I doing something wrong or is MathNet unreliable ?
