I'm solving using modefied euler method, and then finding Jacobian matrix (Fi_x). after running the code it gives me jacobian matrix 6x4. but it should be 6x6 because I have here n=6 and jacobian matrix should be in 6x6 dimension.
kmax=(tc-t0)/h; Xd1=[x0]; Tm1=[t0]; for k=1:kmax t1=k*h;Tm1=[Tm1 t1]; xd=modeu(Fdfp...

How can I add the solutions of xd as a matrix , I tried with xd1 , but it still give an error. and how can I make the new value as a initial value for the next st. x0 known and kmax =10. While the solution should be a matrix of 10 rows .. Thank you !
