MATLAB: Linearization of points problem

dotslinearizationplot

Hello,
I have some data dots which I would like to linearize, however my code is not working.
aMID=[1.780287,3.672423,5.370854,5.363762,7.969255,8.148480,8.374100,10.029387,10.580805,10.781898]
aVenturi=[0.015449,0.032720,3.424873,3.473750,7.594966,6.521211,9.006245,11.045405,11.462227,11.935103]
figure(2)
linsys=linearize(aMID,aVenturi)
plot(aMID,aVenturi,'Marker','o')
hold on
plot(aMID,linsys)
So as you can see, I want to linearize the dots of aVenturi, but it does not work, what am I doing wrong?
Thank you so much for the support!

In this case, the error message clearly tells you what the problem is. 
Error using linearize (line 132)
The first input argument in "linearize" must be a valid model name.
The next step is to look at Matlab's documentation on this function to understand what the inputs are. You can do that by either searching for it on the internet: https://www.mathworks.com/help/slcontrol/ug/linearize.html
Or by entering either of these commands into the matlab command window. 
help linearize
doc linearize   % <-- more detail
The first input needs to be a Simulink model.
Another possibility is that this isn't the function you need (I don't know the goal so I can't recommend anything else).
