How to find a minimum value of a matrix according to another matrix?

1 view (last 30 days)
Hello everyone!!!
I have two 1x10 matrixes named A and B.
A=[1 1 2 3 3 2 4 5 4 5];
B=[0 3 10 6 15 22 23 28 21 25];
I need to find the each minimum values of B while A has different values. For example;
while A is 1, minimum of B is 0
while A is 2, minimum of B is 10
while A is 3, minimum of B is 6
...
I hope you can help me, thank you!!!

A=[1 1 2 3 3 2 4 5 4 5];
B=[0 3 10 6 15 22 23 28 21 25];
[AU,~,AA]=unique(A(:));
MB=accumarray(AA,B(:),[],@min);
[AU,MB]
