I can make my program give the correct answer using the sum(x) function, but i can't use the sum(x) function. is there a way to use either a for or while loop to accomplish the same thing. my present code is:
clc;clear all; close all;w = [1,1.2,.8,1];x = [75, 80, 65, 78];wa = 75;for i = 1:1:length(x); wa(i) = x(i)*w(i); endsum(wa(1:i)./i)
this yeilds the 75.25 answer that i should get. is there some simple that will fix the sum(wa(1:i)./i) I know that i can use the finite fix of wa(1)+wa(2)+…+wa(i), but i need it to work for any number of indexis of wa. as sum(wa(1:i)) does.
