How to make the result of the sum of two vectors in its first element turn out to be 0

Hi. Good morning. I have two vectors A and B

A =

         0    0.2880    0.5659    1.7225    2.3570    3.4754    4.5621    5.4822    5.8049    6.2209

B =

    0.1000         0         0         0   -0.1000         0         0         0    0.1000   -0.1000

the sum of the two vectors would be: C =

    0.1000    0.2880    0.5659    1.7225    2.2570    3.4754    4.5621    5.4822    5.9049    6.1209

What I do so that only the first element of the result in C gives me 0 ? like this

C =

    0.0000    0.2880    0.5659    1.7225    2.2570    3.4754    4.5621    5.4822    5.9049    6.1209

The sum of those vectors does not have a zero sum for the first element. What can you do? Change the vectors, or change the result.

You really have only those two choices, since addition is pretty well defined.

You know what you want to go there, no matter what the first two elements are. So replace that first element in the result with 0. WTP?

Change the value of C(1).

C = A + B;

C(1)=0

Matrix Indexing is a very basic concept in MATLAB. You can refer here for details https://www.mathworks.com/company/newsletters/articles/matrix-indexing-in-matlab.html. After adding C=A+B, set the first element to Zero as C(1)=0.
