Changes in vectors

Hello again.
This is perhaps more a logic question,
If I got measure points at the time t is wrong, and the correct ones is in a vector L_New that has 10 x 1.
How do I do to change the wrong measure points in L to be correct?
I know that I have not post my attempt, but this is more a "thinking" question.
Anyhow, I would be please if someone can tell me how it works.
Best Regards Cillian

This sounds like you may eventually want to interpolate. Do do this, in this case, look into interp1. If you provide us with a small set of sample data we might be better able to help you.

L =[0:10];
L_New =[0:10]';
yi = interp1(L,L_New,'nearest')
% The question is not so clear about if L have the same size or a different size.

Ops, I forgot to add the results:
yi =
NaN
0
1
2
3
4
5
6
7
8
9

Are the measure points located in a vector with the same size like L_New? Or do you have more values?
Same size: Why do you not copy L_New? L=L_New;
Different size: you have to find first the wrong values in L, before you can compare them to L_New and exchange them.

Sorry, I don't know. The question is not so clear about if L have the same size or a different size.
