I am given an array with different numbers and I have to compute the same array but with some values changed.

Hi, as you can see I am gven an initial array "a" and I have to create the code to return the same array but with some values changed according to some requirements I have to meet. Now, I have the values and their index but just do not know how to finish the exercise; I think that I need to use a for loop but I just do not know how to code the last line so that I obtain the same array "a" but with some values changed. Thank you very much in advance.

a = [3 4 5 3 64 7 6 34 8 5 4 3];
m = mean(a);
st = std(a);
an = abs(a - m) > st;
ind = find(an);

Do you mean:

a = [3 4 5 3 64 7 6 34 8 5 4 3];
m = mean(a);
st = std(a);
an = abs(a - m) > st;
ind = find(an);
a(ind) = an(ind)

This one?

a = [3 4 5 3 64 7 6 34 8 5 4 3];
m = mean(a);
st = std(a);
an = abs(a - m) > st;
ind = find(an);
a(ind) = 4   % replace all the meet the requirements with 4
