Some Matlab help
Hi,
I have some equations that i need to solve to see the change of s and x over time. I know i have to use ode45 and matrices but i do not know how to do this. i was wondering if anyone could help me. the equations are: u = 0.25*s/(s+0.005) dxdt = ux dsdt = 0.45*ux I know that i can put u into both equations, then make a matrix with s x as x1 and x2. However i do not now how to input this to use ode45. I was wondering if anyone could help me or point me in the right direction. Id appreciate any help. Thanks Rem |
