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 pdetool for heat transfer, the heat source Q is not a fixed value for me. Suppose I've matrix for Q or a sinusoidal. So how can I set the the value of Q for a variable heat source.
I've a 2d 4 multicorechip. Where each core has different power values and those values are changing with time. These power value...

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...

in MATLAB PDE Toolbox App, I've multiple objects (Rectangular shaped) in one file. For multiple objects I'd like to specify the PDE coefficients differently. How can I specify the different PDE coefficients for different objects.
Additionally I've encountered another 3 problem. 1. What is the difference between Convection heat transfer coefficient(h) a...

in MATLAB PDE Toolbox App, I've multiple objects (Rectangular shaped) in one file. For multiple objects I'd like to specify the PDE coefficients differently. How can I specify the different PDE coefficients for different objects.
As an example, I have 3 rectangular shaped objects. They share the boundary with each other. I'd like to calculate the heat tran...
