I have an 20x1 array of numbers. I know I can use maxk to find the 4 highest values in the array, but if I want to get the linear index values of those 4 numbers how do I do that?
Example of what I mean:
A = [1 2 3 10 8 9 7 4 5 6];
maxk(A,4); gives [10 9 8 7]
If i want the linear indices of 10, 9, 8, and 7 without hardcoding, how can I do that?

Ran in:
A = [1 2 3 10 8 9 7 4 5 6];
[B,Idx]=maxk(A,4)
B = 1×4
10 9 8 7
Idx = 1×4
4 6 5 7
