Smooth function does not available in Matlab 2013a?

Hi,

I was previously used Matlab 2010b to perform data smoothing for Loess Low pass filter. The code was working perfectly with the older version of 2010b, but when I applied the same code with Matlab 2013a, an error shows 'undefined function smooth'. Is there anyone out there can advise on this? Thanks

Do you have the Curve Fitting Toolbox installed and licensed? Try

which -all smooth

See documentation for reference.
