RL = [1;2;3;4;5;6;7;8;9;10];
t = 5;
RL = RL + 10*log10(t);
so this is an example of my code, however i do not want the last equation to include the first value from the original vector and i want it to hold that value. so the new RL vector, the first value is 1 and the rest is some new value based on this calculation.

It seems like you could benefit from taking this introduction to using Matlab: Matlab onramp
This is an example of very basic indexing which you will learn if you go through this simple introduction. to using Matlab.
After you go through that, you will learn that using an index vector allows you to select which elements of a vector are selected.
For your example:
RL = [1;2;3;4;5;6;7;8;9;10];
t = 5;
RL(2:end) = RL(2:end) + 10*log10(t)
This tells Matlab to only modify the elements of RL from indices 2 through the end of the vector RL.
Please take advantage of the free training. Matlab is very powerful if you take the time to learn to use it.
