Answer 2

[Hamzeh Asgharnezhad]

thanks for help

ther are also some other functions start with helper like: helperPlotHistogram

where they are from?

[Brendan Hamm]

I have attached them for convenience. These are all located in the directory created for the example. They can be found in the folder created when choosing the Open In Live Script button at the top of the doc page.

In web browser this will read Try It In MATLAB and provide you the following code line to run in MATLAB 2018b

openExample('predmaint/CentrifugalPumpFaultDiagnosisUsingSteadyStateExperimentsExample')

[Hamzeh Asgharnezhad]

[John Navarro]
