I am trying to use the retime command on a timetable I imported from Excel, but I keep getting this error. I am using R2018a, the function was introduced in 2016a, and the Add-On Manager shows it under the generic Matlab installation, which is obviously present. Another search result from the Add-On Manager shows the function as contained in the Financial Toolbox, which is also installed. Any idea why I cannot access the function? Running

which -all retime

returns

/Applications/MATLAB_R2018a.app/toolbox/matlab/datatypes/@timetable/retime.m  % timetable method

but I cannot access it. Thoughts?

The example simply gives the same error at line 15:

TT2 = retime(TT,'hourly','spline')

Is it possible your classdef of timetable is overloaded or shadowed? Try running and posting the results of these 2 commands:

which timetable -all
methods(TT)

Also, have you confirmed that this problem persists across MATLAB sessions?

In addition to the other suggestions you've already been given, check whether the TT variable is a timetable (for which retime is defined) or a table (for which it is not.)

Depending on how you're importing your data (with readtable?) you may need to convert it from a table to a timetable using table2timetable before calling retime on it.
