Finding corresponding value of one vector in another vector

Hi, for example if I have vectors A = [0 1 2 3 4 5 6 7 8 9 10] and B = [0 100 200 300 400 500 600 700 800 900 1000]. and am getting asked to find the value of B when A=7, how do I do that?

Thank you!

A = [0 1 2 3 4 5 6 7 8 9 10];
B = [0 100 200 300 400 500 600 700 800 900 1000];

result = B(A==7)

result = 700
