Merge two sorted vectors 'a' and 'b' into a sorted vector 'c'

clc,clear all

orga=sort(rand(1,2000000)); % generate 2 million   random numbers and sort them (first vector)
orgb=sort(rand(1,2500000)); % generate 2.5 million random numbers and sort them (second vector)


% % Merging two sorted vectors using 'mergesorted' function

% % Merging two sorted vectors using MATLAB built in functions

    error('problem: report to author')
end

TimeRatio=time_builtin/time_mergesorted
