This is after sorting but with zero values as well.
[a,ind] = sort(totalAmplitude);
bb = [a;ind]';
I want to eliminate the zero values along with its index value as well.
I tried this but this is messing up my original index as well. The index very much needed for me.
[total_amp_temp,index] = sort(nonzeros(totalAmplitude));
ccd = [total_amp_temp index];
I have attached MATFILE as well.

[a,ind] = sort(totalAmplitude);
bb = [a;ind]';
check = find(bb == 0);
bb(check,:) = [];

totalAmplitude(ind == 0)=[];

The index is the most important thing for me, since I'll be using the index for comparision later.
