How to replace values in a matrix according to the reference matrix

Assume matrix A and reference matrix B as follow:

A = [
1
4
8
10
3
2
7
6
3
6
];

% in matrix B two rows has 100 difference.
B = [
1  240
2  340
3  440
4  540
5  640
6  740
7  840
8  940
9  1040
10  1140
];

I want to replace matrix A's array according to the reference matrix B.

C = [
1  240
4  540
8  940
10  1140
3  440
2  340
7  840
6  740
3  440
6  740
];

just

out = B(A,:)

or general case

[~,ii] = ismember(A,B(:,1));
out = B(ii,:);
