Hello, I am trying to use a suggested function to generate a timetable with a sampling frequency of 200 Hz.
tt = timetable(rand(12,1),'SampleRate', 200)
I get an error: Invalid parameter name: SampleRate. This is MATLAB 2017b.
How do we get the desired sample rate?

Here's a link to the 2017b documentation for timetable().
You'll see that there is no 'SampleRate' property. That property appeared first in r2018b.
Here's how to achive your example for releases before and after 2018b.
% 2018b or more recent
data = rand(12,1);
sampleRate = 200; %hz
tt = timetable(data,'SampleRate', sampleRate);
% prior to 2018b
timeSamples = seconds(0 : 1/sampleRate : (size(data)-1)/sampleRate);
tt = timetable(timeSamples', data);

Adam is right, but usually this
is better numerically.
