When solving the Hill's equation,
y''+Ky=0, y=y(s), the prime is the second-order derivative of s.
If we denote the solutions as a vector whose first element is f and second element is f'.
And use a transform matrix M to transform vector y(s0) to vector y(s).
How do we get the property that the Wronskian, W(y1,y2,s)=det(M)W(y1,y2,s0)?
