%% (Internal) Generate a PIDs work list
%
%
% [pid_starts, pid_ends] = TaskPartition( task_size, cant_pid)
%
% Arguments:
%
% + task_size: A positive integer with the size of the job
%
% + cant_pid: The amount of PIDs to work
%
% Output:
%
% + pid_starts: An index array of size cant_pid x 1 with the starting
% indexes for each PID
%
% + pid_ends: An index array of size cant_pid x 1 with the ending
% indexes for each PID
%
% Example:
%
% [pid_starts, pid_ends] = TaskPartition( 10, 2)
%
% pid_starts = [ 1 6 ]
% pid_ends = [ 5 10 ]

%no es recomendable hacerlo mas grande de cant_recs la particion.
