yes , this is what i want to ask, i am sorry for my unclear expression. about the Wronkskian of two first order differential equations such as y1'= ay1+ by2, y2'= cy1+ dy2 the Wronkskian is not det(solution1 solution2)? (two set of solution column vector)

I have just learned the first order system of ODE, i found that the Wronskian in second order ODE is |y1 y2 ; y1' y2'| but in first order system of ODE is the Wronskian is W(two solution), i wonder which ones is the general form? thank you very much
