I have a dynamic system. The equation is ddot = (M)\(F - K*d); Where M,K are (4,4) constant matrix and F and d are vector. I want to solve this equation using ODE45.
In my case The force vector F is variable. The values are changing with time. So to solve ode I've used a for loop. To update th...

In PDE tool What is the difference between Convection heat transfer coefficient(h) and heat transfer coefficient(q)? I know Convection heat transfer coefficient( htc ) but not sure about heat transfer coefficient. Is it the overall htc of the object?
Additionally I've encountered another two problems: 2. In BC parameters, what is weight(h) and temperature(r)? Could you ple...
