function [freq,init,data,varlist,tex] = load_m_file_data(file)
% Loads data in a matlab/octave script.
%
% INPUTS
% o file string, name of the matlab/octave script (with path)
%
% OUTPUTS
% o freq integer scalar equal to 1, 4, 12 or 52 (for annual, quaterly, monthly or weekly frequencies).
% o init dates object, initial date in the dataset.
% o data matrix of doubles, the data.
% o varlist cell of strings, names of the variables.
%
% REMARKS
% The frequency and initial date can be specified with variables FREQ__ and INIT__ in the matlab/octave script. FREQ__ must
% be a scalar integer and INIT__ a string like '1938M11', '1945Q3', '1973W3' or '2009A'. If these variables are not specified
% default values for freq and init are 1 and dates(1,1).
