Machine Learning example function not found- helperLoadData

Hi,

I am a starter of machine learning. In the folling link,

https://www.mathworks.com/help/predmaint/ug/similarity-based-remaining-useful-life-estimation.html

I think there are some non bulit-in functions like helperLoadData

Can someone please tell me where to find this helperLoadData and aslo helperPlotEnsemble ?

Which Release do you have?

Answer 1

[Stephan]

Note that your link refers to R2019b. The example you are looking for in R2019a you find here:

[Tsuwei Tan]

Hi Stephan, I think it is the link. Can you please point out where the helperLoadData is? Thank you!

[Stephan]

Did you try?:

openExample('predmaint/SimilarityBasedRULExample')

[Stephan]

But your problem is not a missing helperLoadData. Did you copy the train.txt file into the working directory, as suggested in the instruction?

[Tsuwei Tan]

Hi Stephan, Thank you so much! I found the example and its sub-functions, now I am able to copy the code and run it. Appreciate your patience.

In varnames clear 'sensor_21'

or clear t(:,end) = []; %Discard last column of loaded data as all are empty ''

Actually helperLoadData.m is another file which can be accessed by entering this in the command window of your Matlab but ensure the version is R2019a or above- "openExample('predmaint/SimilarityBasedRULExample')"
