Homework Help: Matlab help

  1. Jan 22, 2009 #1
    1. The problem statement, all variables and given/known data
    Below are two for loops that each find the mean of all the values in the vector x. A and B should be equal to the mean of the vector x.

    2. Relevant equations



    3. The attempt at a solution
    A = 0;
    for index = mean(x)
    A = A + x(index)/length(x);
    end

    B = 0;
    for index = mean(x)
    B = B + index/length(x);
    end

    A file was provided that checks to see if its right. when i execute it, it says, "Attempted to access x(6); index out of bounds because numel(x)=5." what am i doing wrong? most of the code was already provided. all it asks is what "for index =" is equal to.
