code is too difficult to understand

i have attached a file of the rainflow code can anybody comment this code i cannot understand it from 15 line onward

[Guillaume]

Really? There is nothing complicated about this code.

You can look up the documentation of the few matlab functions that are used ( array2table, convert an array into a table; histogram plot an histogram; xlabel and ylabel, label the axes; figure, create a new figure, rainflow, presumably you know what this does).

If you have a problem understanding a specific line, then please explain what it is you're not understanding.

[N/A]

[c ,hist ,edges ,rmm ,idx] = rainflow(Y,fs);

what does this line does?

[N/A]

actually i am a beginner

[N/A]

histogram('BinEdges',edges','BinCounts',sum(hist,2))

this line as well

Really looking forward to thank you

I'm not sure what you're looking for here. We're not going to teach you matlab, so perhaps you should grab a book and/or read some tutorial (e.g. Getting Started).

[c ,hist ,edges ,rmm ,idx] = rainflow(Y,fs);  

what does this line does?

Assign the output of rainflow (called with arguments Y and fs) to the variables c, hist, edges, rmm and idx. The meaning of these outputs is documented.

histogram('BinEdges',edges','BinCounts',sum(hist,2))

plots the histogram of the sum of hist across the columns, using edges as the x-axis. histogram is documented with plenty of examples.
