Just updated to 2018b, from 2018a, and made sure all the toolboxes I had were downloaded too.
Ran a script that I've been working on that uses the "smooth" function, however it is no longer working and throwing the error:
Undefined function 'smooth' for input arguments of type 'double'.
Is the smooth function no longer supported in the latest update? How can I get around this? The line of code that was working is:
start_filtered=smooth(start,150);
where start is a column vector.
Thanks.

smooth is in the Curve Fitting Toolbox.
Do you have the Curve Fitting Toolbox installed, and a current license for it? Check what is installed:
ver
and check your licenses:

>> which -all smooth
E:\Program Files\MATLAB\R2018a\toolbox\curvefit\curvefit\smooth.m
2018b
>> which -all smooth
'smooth' not found

Is Curvefitting toolbox definitely installed, according to ver?
You might need to reinstall the toolbox.
