Hi guys, I'm having a rough time solving this equation :
dF(i)/dt = -K(i).F(i) + Sum(from j= i+2 to N) of K(j).P(i,j).F(j)
I have the matrix K and the P as well. any suggestings on how solve this equation within matlab? Thank you

is the independent variable "t"? does the summation include the independent variable or is it constant? if so it is a linear first order differential equation. please in order to clarify, attach the image of your equation.

yes, t is independent, only F depends of t. K depends of i (or j) and P depends on i and j.
