I would like to use the apply or a similar function belonging to this
family, but applying for each column (or row) but let say for each q
columns. For example I would like to apply a function FUN for the first q
columns of matrix X then for q+1:2*q and so on. If I do apply (X, 2, FUN) it
applies for each column and not for every q columns. Is that possible with
any similar function?
