Why the function rainflow doesn't work in my MatlabR2017?

Hello,

I am using Matlab R2017a and I am trying to use the function rainflow like in this tutorial: https://www.mathworks.com/help/signal/ref/rainflow.html?s_tid=answers_rc2-3_p6_MLT

But, when I write

help rainflow

This message appears:

In addition when I use this the link below to access this example another error message appears:

openExample('signal/CycleCountsWithKnownSampleRateExample')

According to the documentation page for rainflow, this command was introduced in version R2017b.

Thanks! Could I add just this command in my Matlab2017a?

Generally, no. One typically needs to download/install the new version. However, it may be possible that you can contact support and get the function. I think it would depend on your license agreement, what other functions this one depends on, etc.
