Abstract :
This paper contains the description of the algorithm STCSSP and its interface. STCSSP is a FORTRAN subroutine that computes a structured staircase form for a real (skew-) symmetric / (skew-) symmetric matrix pencil, i.e., a pencil where each of the two matrices is either symmetric or skew-symmetric. An example how to call the subroutine is given.
