Hello, I was wondering if there is any way of using "isoutlier" function in older version of matlab say MATLAB 2011b or MATLAB 2016a ??? This would reduce my working time to program for "Outlier identification" Thank You.

For R2016a, if you have the Signal Processing Toolbox, you can use the hampel (link) function, introduced in R2015b.

This is how you could implement it for previous Matlab versions:
function [av]=Isoutlier(FF)
mk=median(FF);
M_d=mad(FF,1);
c=-1/(sqrt(2)*erfcinv(3/2));
smad=c*M_d;
tsmad=3*smad
av=(abs(FF-mk)>=tsmad);
end

What is 'mad' function?

I wonder if it was "mean absolute deviation"?
