implementing this equation in matlab

[serhannn]

I have to implement the following equation in matlab.. I am trying to do it using a for-loop but I get an error since the initial value of L=0.
How else can I implement it?

The equation is:

​

The code I'm using and getting an error:

for i=1:L
      delta = s(k) - lambda_prev(1+i)*(s(k-i))';  
end

Make your for loop i=0:L
As long as you aren't calling or assigning to an array element zero, like s(0)... then your code should work.

Additionally, you could shift everything by 1, making the loop run 0 to L, but where ever you have "i", change it to "i+1", so the first time through the loop you'll always have i+1 give you a 1, and not a 0.

Without seeing more of your code, its tough to say which method will work best for your situation.
