Hi..I have a question: if I have the result of a wavread, an array of samples, and I want to search the minimum element only between the last hundred elements and its index, how I can do this? I have some problems with the indices.

v=rand(150,1)
[a0,idx0]=min(v(end-100:end))
% a0 your min
% idx0 corresponding index

array=rand(20,1)
[L C] =size(a)
lower=min(a((L-10):end))

Hello Micaela
Step 1 Data
Data=randn(100,1);
Step 2 Find the min in Data
Index = 10; %Search in the last 10 data
x=min(Data((length(Data)-Index):end,:));
Step 3
Description row, column, index of min data
[r,c,v]= find(Data==x);
In this case, r=row vector; c=column vector; v=index value
Hope it helps.
Javier
