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.

Hi

I am not able to use this.

I am new to Matlab, can anyone help and let me know how to use this for the set of my data or any data for that matter.

Regards

Hello

I'm running the tool, and it works very well! Thank you!

But why you describe the cycles with Amplitudes and not Range? Is it correct, to multibly the amplitude by 2 at the end to get the range?

(2*mx) to get the
associated range?

If you are running MatLAB R2012b on a Macbook you can follow the link below in order to use the rainflow.c script:

http://www.mathworks.se/support/solutions/en/data/1-FR6LXJ/

It will guide you how to install Xcode, patch it and then you are ready to compile your mex file for Matlab by writing this in your command window:

mex rainflow.c

I'm currently running MatLAB R2012b on my Macbook Pro, but I'm having trouble running the script. Is there a rainflow.mexOSX? When I'm running rfdemo1.m it gives me this error:

Undefined function 'rainflow' for input arguments of type 'double'.

Error in rfdemo1 (line 35)
a=rainflow(ext,1);
