Get the position of the max and min values of a variables

1 view (last 30 days)
Hi, so I want the position of the maximun values of a variable my code is:
pos = 1:numel(lat1);
b = maxk(lat1,5);
% index = pos(b);
When I use the line of code indez = pos(b) I get the following error:
Array indices must be positive integers or logical values.
I dont get why. Can somebody help me?

[b,index] = maxk(lat1,5);
% ^^^^^ the second output is the index
