Hi.
I could use some help here.
There is a zeros array, where I would like to replace some elements that have certain positions with the values from another vector. So, if I have:
A=[0 0 0 0 0] %Zeros vector
B=[5 6] %values
C=[2 5] %positions of elements in A that should receive a new value from B
How should I get a vector D=[0 5 0 0 6] ?
I appreciate your helping!

for i=1:3
x=[1 2 5];
y=zeros(1,3);
y(1:1:3)=1+log(x(i));
end
Please help replace each entry of y by 1+log(x(i)). That is I want y=[0 0 0] changed to y=[1+log(x(1)) 1+log(x(2)) 1+log(x(3))]
