Solving Matrix differential equations

Hi team I found your great way to solve matrix riccatti equation by you in the below link. http://au.mathworks.com/matlabcentral/answers/94722-how-can-i-solve-the-matrix-riccati-differential-equation-within-matlab My problem is also somewhat related to it. But a small difference. dK/dt =W(t) * K (t) - K (t) * W(t). Here both K and W depends on time. Can you please help me to solve this?

How does W(t) depend on time? I.e., what is preventing you from simply calculating it inside the derivative function given t?
