comment How to deal with matrices involved in system of SDEs?
It is now done. Can anyone give even some general hints or codes for dealing with system of SDEs?

comment Why doesn't FullSimplify work properly on this?
Note that $1+R+R^2+R^3+R^4+R^5+R^6$ requires 5 multiplications to be implemented, while $1+(R+R^4)(1+R+R^2)$ requires only 3! That is why a more factorized form is desirable.

comment How can you compute Itō Integrals with Mathematica?
Well done. Can you implement the Euler-Maruyama or SRK method for finding the weak solution of Black-Scholes SDE in Mathematica?

comment Is there any fast way to solve a quadratic matrix equation in Mathematica approximately?
The applied norm is optional (Frobenius or Infinity). Just finding some approximate valaues for the scalars in any fast way is needed.
