Dear all, I have a 2505*1 vector with only 1 and 0. The number 1 occurs 178 times. I want to delete the first 158 rows with an 1 and the last 20 rows and the rows with 0 should stay! How can I do that? Thank you in advance!

rowsWithOnes = find(vector == 1)
vector(rowsWithOnes(1:158)) = []; % Delete first 158
vector(rowsWithOnes(end-19:end)) = []; % Delete last 20

idx=find(A)
idx1=[idx(1:158) idx(end-19:end)]
A(idx1)=[];
