MATLAB: Modify the given vector x=[1.1 1.4 1.9 2.1 1.3 1.7 1.8 5 1.5] by elimination of values that differ by more than the standard deviation from the mean value of the given sequence.

modify the given vector

Could you please provide me some solution for this question? Possibly using loops. Mean =2.0 ; Stdev = 1.2;

Feeling loopy tonight, but not that loopy!
Try this, avoiding the loopys:
x=[1.1 1.4 1.9 2.1 1.3 1.7 1.8 5 1.5];
x_mean = mean(x);
x_stdv = std(x);
limits = [-x_stdv  x_stdv]+x_mean;
x_dev = (x<=limits(1)) | (x>=limits(2))             % Logical Vector wheren ‘1’ (True) Meets The Criteria And ‘0’ (False) Fails To  Meet It                                                     
_dev =
    1×9 logical array
     0   0   0   0   0   0   0   1   0
