Hi i have to solve a system of 10 differential equations, however the equations are not directly given to me.
I have to derive the equations with the help of a separate code (basically enegy balance across 10 adjacent layers). I have used syms function to initially define all the temperatures as a function of time and then written their respective equations such that the result of this code helps me to identify my equations (such that dT1/dt = f(T1,T2,T3----T1(1),T1(2), in other words when i display my equations, the derivative of temperature wrt to time is a function of temperatures of the layers and also temperature of the particular layer at a particular time)
Now I would like to know how to use solve these equations simultaneously . What solver to use, I tried using ode45, but am not able to call the variable appropriately such that it suits the format.
