How to find a value of a vector from another one?

7 views (last 30 days)
There are two (A&B) vectors with N samples each. Each number of A has a specific value in B.
I have a value in A (a number among N samples), and interested to find it in B. For example:
A=[250 400 300 200 100 ...]
B=[5 6 1 2 9 ...]
I want to find B when A =200, the answer is B=2 (in this case).

I thought it is much more complex and need to use arrayfun.
Thank you
