For example, I have this column vector:
A =
0
5.1205
5.6338
0
2.9639
5.6774
0
2.6281
0.7772
2.5641
I want to remove other rows and take only rows where the index is from a vector
B =
2
3
5
6
8
9
10
So, it will become
C =
5.1205
5.6338
2.9639
5.6774
2.6281
0.7772
2.5641

Very basic MATLAB concepts, such as how to use indexing, are explained in the introductory tutorials. These are highly recommended for all beginners:

Hi Jerry,
Matlab documentation is your friend:
C = A(B)
Kind regards,
Robert
