关于MATLAB定时器的问题

[huamengxianjue]

function NCC_OpeningFcn(hObject, eventdata, handles, varargin)
loadlibrary('pluse','pluse.h'); %加载动态链接库
t=timer('TimerFcn',{@TimerFcnCallBack,handles}, 'Period', 0.01,'ExecutionMode', 'fixedRate');
start(t);%开始执行
handles.output = hObject;
guidata(hObject, handles);
function varargout = NCC_OutputFcn(hObject, eventdata, handles)
varargout{1} = handles.output;

function TimerFcnCallBack(hObject,eventdata,handles)
xp=calllib('pluse','getpositionX');
yp=calllib('pluse','getpositionY');
zp=calllib('pluse','getpositionZ');
set(handles.xzhou,'String',xp);
set(handles.yzhou,'String',yp);
set(handles.zzhou,'String',zp);

运行时总是出现'Error while evaluating TimerFcn for timer 'timer-1''
Invalid or deleted object
