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

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.
