Objective function with 1,000 variables

Hello, I want to write an objective function which is composed of 1,000 variables. Can someone help me to do this. (My objective function is the following: r1+r2+...+r1000). Thank in advance. Hiba.

Assuming that your coefficients are presented as row vectors, and that you might have multiple rows representing different locations being sampled:

objfun = @(x) sum(x,2);
