substituting values into an array

Question

Morten Jensen 2011-6-21

Hi

I need to substitute some values from one arry into another but is getting the error:

??? Subscript indices must either be real positive integers or logicals.

The arrays in question as well as my current attempt are as given below:

K = 130;
T = [0 33 57];
V = [0.9 0 .5];
period = ones(2,K);
period(1,:) = 0:K-1;
for i = 1:size(T,2)
    period(2,T(1,i):end) = V(1,i);
end

Can anyone help me with this problem?

You can't have period(0), it tries to reference this when

i = 1
period(2,0:end); %substituting T(1)

Start your indexing at one instead. Keep a reference vector (like T) if you need to know what period(x) corresponds to.
