Error when I execute bitshift

I get error information when I try to execute bitshift:

Attempt to execute SCRIPT bitshift as a function: C:\Program Files (x86)\MATLAB\R2013b\toolbox\matlab\ops\bitshift.m

Error in wdq_to_txt (line 73) ad=bitshift(adc_data,-2);

I use small code to test bitshift like this: a=[-32727, -5059]; b=bitshit(a,-2); I get same error.

I read matlab help on it, it seems no problem. Please help.

Your installation appears to be corrupted. You should reinstall MATLAB.
