  Procedures to recover explicitly discrete and continuous skew-selfadjoint
Dirac systems on semi-axis from rational Weyl matrix functions are considered.
Their stability is shown. Some new facts on asymptotics of pseudo-exponential
potentials (i.e., of explicit solutions of inverse problems) are proved as
well. GBDT version of Backlund-Darboux transformation, methods from system
theory and results on algebraic Riccati equations are used for this purpose.
