There is no need to use any for loops. Just use colon operator to extract a particular column from the matrix (formed after importing data from excel). Later, use that column as an input to the filter.

data         = rand(2562, 11);
[b, a]       = butter(8, 0.4);
data(:, 3)   = filter(b, a, data(:, 3));
data(:, 6:8) = filter(b, a, data(:, 6:8));

What exactly is the problem?
