How can I get the linear indices of the 4 maximum values of an array?

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?

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
