Return specified rows of a vector
显示 更早的评论
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!
