Happybird,

Do you have MATLAB installed on the computer?  LabVIEW makes calls to MATLAB to run the script node.  If so, make sure that you have launched MATLAB and then launch LabVIEW.  Once you have tried that, <a href="http://digital.ni.com/public.nsf/websearch/4475BC3CEB062C9586256D750058F14B?OpenDocument">KB 300A6NDT</a> might be helpful.  Hope this information helps!

Yes,the matlab 7.1 sevice pack 2 is installed on the computer,and i did not have any problem when use matlab for this program.

So you are able to implement the same function by calling it using .m files in MATLAB?  LabVIEW makes ActiveX calls to MATLAB to get the communication to work, so if you are able to call the function in MATLAB you should be able to use it in LabVIEW.  I also might recommend making sure that you have the .m file in the correct path, or that you have assigned the path for that file in MATLAB.
