[t1,t2]=time(command)

function [t1,t2]=time(command)
% TIME('command')  records time consumed to run 'command'
%
%     Without output arguments, displays a message in the MATLAB window
%     indicating how much CPU and Wall Clock time it takes to run 'command'.
%
%     CPU=TIME('command') returns the amount of CPU time consumed.
%     
%     [CPU,WCLOCK]=TIME('command') returns the amount of CPU and Wall Clock
%     time consumed.
%
%     Note that the Wall Clock time is more sensitive to system load than is
%     the CPU time.
%
%     Use TIMESIM to time Simulink models.

%     See also TIC, TOC, CPUTIME, TIMESIM.
