a third order solution is when you develop ( like a series taylor for example); till the third order. I need the third order only. in this example, we can solve analytically using some approximation but i need the program to extend to my problem ( which is more complicated)
Matlab can solve a set of non linear coupled equation; I want to find the third order solution, does anyone have a typical program for such Problem:
dx11/dt=a*x11*y12+b*y12
dy12/dt=c*y12*x11+d*x11
where a , b,c,d are constants
I want to see just the third order solution
