Hi Cuong,

First, please use a [math] marker on the subject line when posting to
this list for the commons-math component. The list is shared among
several commons components and these markers help filtering.

You can use the linear algebra packe from commons-math with complex
matrices. The appropriate interface is FieldMatrix<Complex> which has
two implementations: Array2DRowFieldMatrix<Complex> and
BlockFieldMatrix<Complex>. The former should be preferred for small
sizes and the later for large sizes. You can also use complex vectors
and LU decomposition with these matrices.
