How to use filloutliers for only positive numbers of a data array?

so if data is stored in Variable 'a'

a = [ 2 1 23 -1 2 5 -36 6 -1]

so it should perform filloutliers only on positve number

when i use b = filloutlier(a) it repalces both '23' and '-36' but i wish it should only perform functionallity on positve number that is '23' and ignore negative numbers.

one method is to filter the data and stored them in a seperate variable or secondly we can remove negative values but because variable 'a' is accessed on many occasions in code so want to perform this on variable 'a' instead of a new variable,

Lets say if i do a(a<0) = 0,

then b = filloutlier(a,'Linear');

it give filloutlier of only positive numbers but my orignal data is change..

kindly suggest a solution... if i again summarize my question basically i want to remove only positve peaks in my data...

Try this

a = [ 2 1 23 -1 2 5 -36 6 -1]
a(a>0) = filloutliers(a(a>0),'Linear')
