Hi all,
the above error emerges also when I try the ssimple toy example in the help of ssmooth function. I am on Mac OSX Catalina and using R2020b.
Why iss this happening?
Thank you,
Federico

Hi, could you please share a minimal example to reproduce the error?

The message tells you, that there is a problem with calling the function. Then show us, how you call the function. What are the inputs?

Do you call the built-in function smooth or did you shadow it with a user-defined function? See:
which smooth -all
Please post a small working example. Does the message occur for this also:
smooth(rand(1, 100))

Hi Jan, I got the same problem and I don't know how to solve. Could you please help me with that? Thank you in advance!
When I run the code you recommend, I got:
>> which smooth -all
/Applications/MATLAB_R2021a.app/toolbox/econ/econ/@ssm/smooth.m % ssm method
/Applications/MATLAB_R2021a.app/toolbox/econ/econ/@msVAR/smooth.m % msVAR method
/Applications/MATLAB_R2021a.app/toolbox/econ/econ/@statespace/smooth.m % statespace method
/Applications/MATLAB_R2021a.app/toolbox/econ/econ/@dssm/smooth.m % dssm method

>> smooth(rand(1, 100))
Check for incorrect argument data type or missing argument in call to function
'smooth'.

You do not have a smooth function for type double. Perhaps you are missing Curve Fitting Toolbox

Thank you Walter! I install the Curve Fitting Toolbox, and the problem is solved.
