MATLAB: Index exceeds matrix dimensions error.

indexindexing

Hi, I would like to know how to change the 0's in C that are in the same position where d1 finds values where (d<=d0) with the corresponding d2 value. d is a 100×1 array and d0 is the mean value. For instance if the first and fourth elements in d are less than d0, then the first and fourth elements in d2 are stored as the first and fourth elements in C respectively.
    C=zeros(100,1);
    d = randi(10, 100, 1);
    d0 = mean(d);
    d1=find(d<=d0);
    d2 = randi(10, length(d1), 1);
    C(d1)=d2(d1);

You should just be able to replace that last line with
C(d1)=d2;
You have already trimmed d2 to the size of d1 in the previous line.
