sylv:
Syntax: sylv ( A , B , C )
sylv ( A , C )
Description:
Sylv solves the Sylvester matrix equation.
A*X + X*B = -C
or
A*X + X*A' = -C (Lyapunov equation)
A and B must both be upper quasi-triangular (if real), or
triangular (if complex).
If A and or B are not upper quasi-triangular/triangular, then
it is usually easier to use lyap. Lyap performs a Schur
decomposition on A and B before using sylv.
Sylv uses the LAPACK functions DTRSYL, or ZTRSYL.
