let's say that i have a vector of yhat =506x1 and i have an h = 3 value

how do I remove the first 3 elements and the last 3 elements of yhat so that it will be a 500x1 vector.

I currently wrote, yhat(h+1:end-h); but it gives me 6 zeros for the last results, and that is not what i want.

How do i fix this? I just want a new vector of yhat where it is 500x1 because I removed the first 3 and last 3 elements based on the size of h. thank you!

Thank you verym uch

在 MATLAB Online 中打开

Reassign in place...

yhat=yhat(h+1:end-h);
