Default steadystate method ("direct") fails with singular matrix in piqs.Dicke

When using the 'piqs.Dicke' class to compute the steady state, the default 'steadystate' method (method="direct") raises a "ValueError: Matrix is singular" error ...

Solution of impedance matrix localization form of moment method problems in five iterations

Abstract: The impedance matrix localization (IML) method replaces the usual full N × N moment method matrix by a sparse N × N matrix. Typically, this matrix has about 50N nonzero elements. Iterative ...
