etime.m

信号实验常用的simulink模型和mfile,可直接在matlan下运行。

function t = etime(t1,t0)
%ETIME  Elapsed time.
%   ETIME(T1,T0) returns the time in seconds that has elapsed between
%   vectors T1 and T0.  The two vectors must be six elements long, in
%   the format returned by CLOCK:
%
%       T = [Year Month Day Hour Minute Second]
%
%   Here's an example of using ETIME to time an operation:
%
%     t0 = clock;
%     operation
%     etime(clock,t0)
%
%   Caution: As currently implemented, it won't work across month or year
%   boundaries.  It is an M-file, so it can be fixed if you require this.
