Correct way of using if-Function

Hello,

im using a for loop to iterate through a vector filled with n element from 1-6.

What i want it to do:

Iterate through all element and check for each of them:

IF the value is less than 3, save them in an new vector and add 3

Else just add the number to the new vector

The solution should be: x = [4 5 3 4 5 3 4 5 3 4]

right now this is what i get: x = [4 5 3 1 2 3 1 2 3 1]

Whenever the first if-statement is not current it breaks

clear
v1 = [1 2 3 1 2 3 1 2 3 1];
v2 = [1 2 3 1 2 3 1 2 3 1];
Stop = length(v1)
x = []
for i = 1: length(v1)
    if (i < 3)
        x(i) = v2(i) + 3
    else 
        x(i) = v2(i)
    end
end

The problem is that you are using the index i instead of v1(i) (or maybe it should be v2(i) - no way to tell) in your comparison "if (i-3)". You want to compare the value, not the index of the value, so it should be "if (v1(i) < 3)".
