COMPleib: COnstraint Matrix-optimization Problem library

COMPleib is a collection of test examples. The library can be used for testing and benchmarking algorithms for
  • linear semidefinite programs (SDPs)
  • nonlinear semidefinite programs (NSDPs)
  • minimizing spectral functions
  • Lyapunov/Riccati equations
  • control system design and related matrix problems
