OrderedComplexEigenDecomposition user defined sorting

[axkr]

The fields eigenvalues and eigenvectors in ComplexEigenDecomposition didn't get sorted in OrderedComplexEigenDecomposition.
Only D and V get sorted.

How can I define my own sorting and get these fields also refreshed?

Is is a bug.
I have fixed it in master branch, could you check if it works for you now?

[axkr]

Can you also introduce a constructor for

public OrderedComplexEigenDecomposition(final FieldMatrix<Complex> matrix, ...)` 

parameter?

[maisonobe]

Not easily.
We don't have eigen decomposition implemented in the general case, only in the real case (which however does provide
results as complex numbers when the real matrix has complex eigenvalues).
Could you open a new issue labeled as "Feature" to ask for implementing this feature?

Done #174
