% The parameter "scale" determines how long the benchmark runs;
% typical values are: 1 for small size input 
%                     10 for medium 
%                     100 for large.
%
% The function "set_up_bmark" sets up the input data for the 
% benchmark, "bmark". This function must be defined for each 
% benchmark. The set_up_bmark accepts scale as the only parameter. 
% The value of the scale is used to manipulate the input size to 
% obtain the right size as described above. The function must also 
% return suitable values for the input parameters of the benchmark.
%
% The number of the output parameters of set_up_bmark must match the 
% number of the input parameters that the benchmark (bmark) expects.

% The variables t_0, t_1 and t_2 record the time at different stages 
% of the benchmark.
