Specifying values in 2D array when I know the indices

I have the short example below. With the max function I find the indices of the maximum values whithin each column of array A. I want an array C which will include the values of array B by using the idx values I specified before. So, C will be C = [1 2 3 4 5]. How can I do that without a for-loop?

A = [1 1 1 1 100;
     100 1 1 1 1 
     1 1 100 1 1
     1 1 1 100 1;
     1 100 1 1 1];

[~,idx] = max(A,[],1);

B = [1 1 1 1 5;
     1 1 1 1 1 
     1 1 3 1 1
     1 1 1 4 1;
     1 2 1 1 1];

A = [1 1 1 1 100;
    100 1 1 1 1 
    1 1 100 1 1
    1 1 1 100 1;
    1 100 1 1 1];
[~,idx] = max(A,[],1,'linear')

idx = 1×5

2 10 13 19 21

B = [1 1 1 1 5;
    1 1 1 1 1 
    1 1 3 1 1
    1 1 1 4 1;
    1 2 1 1 1];
C=B(idx)

C = 1×5

1 2 3 4 5
