I am using a library called ejml (Efficient Java Matrix Library) and I am having some trouble trying to calculate the dimension of the nullspace from a Matrix.
First I tried with Singular Value Decomposition, but it gave me the error: "Decomposition failed".
And now I was wondering if working with QRPDecomposition could work.
But I dont know how to work with that library / how to make a matrix and calculate the nullspace. If you could put me some examples I will really appreciate
