- 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.
