Other MATLAB functions operate essentially on a vector (row or column), but act on an m-by-n matrix () in a column-by-column fashion to produce a row vector containing the results of their application to each column. Row-by-row action can be obtained by using the transpose; for example, mean(A')'. A few of these functions are
