how to create a vector of variables

hi all,

I'm trying to use genetic algorithms to maximize a fed-batch fermentation product concentration by manipulating the feed rate of a substrate. what I have a problem with is how to define this feed rate throughout the fed-batch reaction. the time of reaction is 10 days, and i'd like to break this into 10 intervals (1 day per interval) so i can have a particular feed rate per day. With that said, how do i create a feed rate vector that has 10 feed variables for each of the 10 time intervals.

if the feed vector is

P(g) = [P1(g) P2(g)...Pi(g)] such that i is the number of the intervals within 10 days.

each of Pi(g) variable is then passed to the GA function for optimization of that time interval in the non-linear fed-batch system.

please help, D

But perhaps it would make sense to use a 2D array? Pa(g, i) ? Then Pa(g,:) would be your P(g)
