Previously, I found some article discussing on using Krylov subspace to solve the following Lyapunov equation: A X + X A T = b ⋅ b T. where b is a vector. Due to b ⋅ b T being a rank-one matrix, Krylov subspace appraoch is highly efficient. Now in my case it is the identity matrix I, but X in my case is symmetric.
