HbO_index = find(xyz1 > 7.5);%link the index with the HbO table and eliminate the bad channels
HbO_good_channel = HbO;
% for i = 1 : size(HbO,2)
for l = 1 : length(HbO_index)
k = HbO_index(l);
HbO_good_channel(:,k) = [];
% end
HbO_index is matrix containing values which are basically index of HbO_good_channels which i want to remove.
Only the first column from HbO_good_channels it removing properly rest its removing one index prior to what is actually mentioned, it something to do with my logic. help me out please.
thank you

The problem is that in your for-loop you delete the l-th column. Thereby all the indecies of the following columns change (are reduced by one). This happens in each iteration of the for-loop. If you want to remove columns "a, b, c, d" with your code you will actually remove columns "a, b+1, c+2, d+3".
You can solve your problem by starting the for loop on the end of "HBO_index" or without a for-loop:
HbO_good_channel = HbO
HbO_good_channel(:,find(xyz1 > 7.5)) = [];
