Hello,
I have been trying to reorganize my variables & parameters into struct arrays in order to group all corresponding to a same physical quantity (like temperature.air pressure.atmosphere etc.)
Some of these parameters are used in an ODE system (see below) and seeing the error I realize that I might have to abandon my idea of using struct arrays... Please let me know what I missed :)
Also, I would be happy if someone can send me some good literature on the proper use of struct arrays for modeling.
Thanks!!
