To anyone out there who may be able to help

I have been researching into closed-form solutions of the 2 x 2 case of the Matrix Differential Equations

dM(s)/ds = [ M(s) , D(s)/2 ]   ,    M(0) = Mo in sl(2,R)  ( 1 )

dD(s)/ds = [ M(s) , K(s) ]      ,     D(0) = Do in sl(2,R)  ( 2 )

dK(s)/ds = [ D(s)/2 , K(s) ]    ,    K(0) =  Ko in sl(2,R)  ( 3 )
