Assuming i have a vector

A = [ 7.7 213.1 9.5 227.5 12.5 6.8 100.8 5.3 7.2 99.4]

I want to pick a value that is maximum and is greater or equal to the index 5.

In this case my answer would be 100.8 and is of index 7.

Thanks in advance

m = 5;
[value,ii] = max(A(m:end));
index = ii + m - 1;

If i want to pick say three highest values from the vector A together with their index, How do i go by it? In this case the values to be selected will be

 val = 227.5 213.1 100.8
 idx = 4     2      7
