Hi,
so i have an array W = [11, 56, 22, 45, 29]
then i use Z = mink(W,2) to find the 2 lowest numbers in W
how do i output the position of the numbers found in Z from the array W?
I tried find(Z) but i got the positions of the numbers in array Z, not their position in array W
For this exemple i used small numbers but the actual W has more then 200 numbers so typing a code for each would take forever

Ran in:
You can specify a second output argument to get the linear index of the elements represented by Z:
W = [11, 56, 22, 45, 29]
W = 1×5
11 56 22 45 29
[Z idx] = mink(W,2)
Z = 1×2
11 22
idx = 1×2
1 3

If you find that the answer has sufficiently satisfied the question, you can accept the answer. This moves it to the 'accepted' queue, where it may be more visible to the next person looking for help with the same problem.
