You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: ste.m
    path of file: ./repos/CanlabCore/CanlabCore/Statistics_tools
    
    the code of the file until where you have to start completion: function [my_ste,t,n,p,m] = ste(dat)
% :Usage:
% ::
%
%     [my_ste,t,n_in_column,p,mean] = ste(dat)
%
% standard error of the mean
% and t-values, columnwise
% and p-values, if asked for
%
% omits NaN values row-wise within each column
%
% does NOT use n - 1
% matches matlab t-test function
