dll已加载成功并且能调用一部分函数，调用'ReadWavelength'直接挂我该怎么办？

try

if~libisloaded('OpticalDevice')
      loadlibrary('OpticalDevice','OpticalDevice.h');
end;
m = libfunctions('OpticalDevice','-full');%显示库中函数
% libfunctionsview OpticalDevice;%显示库中函数
sSerialNO ='123';
pCharSerialNO = libpointer('cstring',sSerialNO);

%p = libpointer('stringPtr');
nNumPixels = 0;
sSerialNum='';%序列号
bSuccess=calllib('OpticalDevice','OpenDevice');%打开设备是否安装了驱动？ usb插拔一下？
if bSuccess==0
      msgbox('打开设备失败','警告');
else
      nNumPixels = calllib('OpticalDevice','GetNumPixels');%调用成功
   % calllib('OpticalDevice','GetSerialNO',pCharSerialNO); %调了就崩溃

%%调用'ReadWavelength'直接挂
   wavelength = 0.1:1:10000;
   pWavelength = libpointer('singlePtr',wavelength);
   bSuccess = calllib('OpticalDevice','ReadWavelength',pWavelength);%运行到这里Matlab直接崩溃弹窗（Matlab system error）
   %'[bool, singlePtr] ReadWavelength(singlePtr)'

   if bSuccess==1
         disp('读取波长成功');
   else
         disp('读取波长失败');
   end
end

bSuccess=calllib('OpticalDevice','CloseDevice');
unloadlibrary('OpticalDevice');
catch exception
bSuccess=calllib('OpticalDevice','CloseDevice');%关闭设备
unloadlibrary('OpticalDevice');%释放库

disp(exception);
end
