Abstract
- Two questions about the existence of structured matrices with given linesums and given zero–nonzero patterns are settled: when is there a symmetric matrix and when is there a skew-symmetric matrix? The solutions use some ideas from prior treatment of the analogous problems without structural constraints, but the current results require new conditions and new methodology.
