You are the best! The tool is simple and do exactly what I have expected. Thank you.

Hi Dilip Rao,
You can add the matrices without problems if they have the same size: m=m1+m2+m3. I don't know what you need exactly to do, but be careful while adding matrices from different sensors - maybe you have multiaxial fatigue problem? I this case use some theoretical criteria for obtaining equivalent uniaxial fatigue loading/matrix.

Hi Andrew Greaser,
The RFHIST counts cycle amplitudes and not ranges. You can also make an histogram for cycles mean, frequency and period. See help lines included in RFHIST function.

According message from Scott Richardson, 09 Oct 2010.

There are more than one equation for stress-life characteristics. Probably you are working with the Basquin model:

    Sa=Sf*(2*Nf)^b

where b is understood as the curve slope. In my example the Wohler model is used. It is possible, with some restriction, compute the 'm' slope on the basis of Basquin model:

    m=-1/b

But remember that the first step is clarifying which kind of curve you are using. The Miner rule n/N=1 is used anyway.

Best regards, Adam Niesłony

17 Jan 2012 Rainflow Counting Algorithm Very fast rainflow cycle counting for MATLAB Author: Adam Nieslony PARK, JAEWOO

Dear Adam,

Thank you for your advice, I got the results I wanted from rfdemo1. But I don't know how to get similar results like 'amplitude, mean, number of cycles (cycle or half cycle), begin time of extracted cycle or half cycle, period of a cycle' using rfdemo2. I need to input a lot of data and get the results like list in rfdemo1 using input data like vibrations. Thank you a lot.

Best regards

Jay Park

dear Adam,

hi~ I started to study MATLAB just before. I got a problem that I can't input a data to your algorithm. Can you give me an example with inputing some numbers?

Thank you

I wanted to do it, you already did it... perfectly. TY.
