Return specified rows of a vector

Hello,

I've tried searching for a solution to my problem, but I'm afraid I couldn't find anything. I'm hoping someone can either point me in the right direction, or help give me a hint here :)

Say I have a vector of data A

A = [4;8;2;3;8;6];

And I have a vector of specified rows i

i = [1;3;5;6];

How do I return a vector B, which is the specified rows of A as specified by i, like below?

B = [4;2;8;6]

I've been trying various logical operations, but haven't been able to figure it out yet.

Thanks for the help!

Try

A = [4;8;2;3;8;6];
i = [1;3;5;6];
B = A(i)

I knew it would be something stupidly simple that I failed to see :)

Thanks so much!
