d = xlsread('FaceFour_TRAIN.xlsx')
s = d(1:1,2:end);
fa = movstd(s,20,1);
secarray = movstd(fa,20,1) ;
secidx = find(secarray>.04);
f = secarray(secidx);
[maxvals, maxidx] = maxk(f,14);
sidx = secidx(maxidx);
x = 1:length(s);
key=plot(x, s, 'b-', sidx, s(sidx), 'go')
here the maximum points are extracted and plotted.I need to check and find only the extreme points from this,how can I do this.Please help me.

I suspect some combination of islocalmin, islocalmax, and/or ischange will identify the points you've called out with + markers in your plot. All three of these functions were introduced as part of MATLAB in release R2017b.
