Bug in MathNet.Numerics.Providers.LinearAlgebra.ManagedLinearAlgebraProvider line 758

In the method "public void LUFactor(float[] data, int order, int[] ipiv)", you have in your code:

// Compute multipliers.
if (j < order & data[indexjj] != 0.0)
{
...
}

You are missing the second & in your AND operation - otherwise you are doing a bitwise AND instead of the logical AND which is what you want. In your case it might actually work but it is misleading and error prone. It should be:

// Compute multipliers.
if (j < order && data[indexjj] != 0.0)
{
...
}

Cheers!
