I'm really new to Matlab, and hope someone can help me!
I tried to use the function 'filloutliers' to remove and replace the outliers, but i want to detect outliers by 2.5 standard deviation instead of 3 (default).
Is it possible to do that by filloutliers, or should i use other functions?
i saw someone used plot to remove outliers, but i don't know how.
Looking forward to be answered, thanks in advance!

Looking at the help in
doc filloutliers
this should work:
filloutliers(A,'center','mean','ThresholdFactor', 2.5)
replacing A with whatever your array is called.
