Inegrating systems with changing spring rate
I am trying to integrate a system using ode45 in which the spring rate changes with system deflection. Is there a way to use ode45 for this? I would need to check the preious iteration and see if the deflection (x) has reached a certain point. If it has, then a new spring stiffness is used. Is there a way to check ... 7 Mar 2010 11:48

Finding the mean in a matrix: how to go from a 1km to a 5kmresolution
Hi everybody, I'm struggling to convert a matrix which represents 1km resolution data to 5km resolution. What I want to do is convert every 5x5 block to one value, by taking the mean-value of these 25 cells. Is there an easy way I can do this? (tried it with mean function, e.g. value=mean(1:5,1:5), but couldn't m... 7 Mar 2010 10:41
