Is there any explicit stable method to solve stiff ODE systems?

I'm solving stiff ODE systems, like y' = My + f where M is a large constant matrix and f occasionally changes. I know that explicit (forward) Euler, RK4 and other usual explicit...

What are the best numerical methods to solve large linear ODE systems?

Could someone suggest methods/algorithms to solve a system like y' = My + f where M is a huge matrix? Most explicit methods (like usual RK4) require very tiny timesteps for stiff systems, implicit...

When the diffusion-type PDE is valid for the electric potential?

I'm looking for the electric equivalence of the (second order linear parabolic) heat equation in order to calculate transient processes. At the phenomenological level, there is a strict analogy...
