error detects in labs in spmd

I have problem with this code , I can not know what is the reason.
this error what I got:
Starting matlabpool using the 'local' configuration ... connected to 2 labs. Lab 2:
??? Error using ==> spmd_feval at 8 Error detected on lab(s) 2
Error in ==> test at 7 Nofusers=700;k1=1;
You must call TIC without an output argument before calling TOC
without an input argument.
(No remote error stack)
%%%the code%% clc;clear;close all;
N=2; % Number of your CPU core, in my case, 4
matlabpool(N) % open N multicores for the parallel computation
spmd % similar with for loop
matlabpool close % you must close the multicore calculation statement

Your nesting appears to be off. You have the "matlabpool close" and the "toc" before it inside the spmd block.
Each lab is effectively a different MATLAB session. The "tic" before the spmd block is not in the same session as the "toc" inside the spmd block.
