11 Nov 2009 Rainflow Counting Algorithm Very fast rainflow cycle counting for MATLAB Author: Adam Nieslony Lee, Jinsuk

I have temperature data over time and derive a fatigue model. Using this rainflow counting, I want to get data with three parameters, which are Max_termperature, each cycle time, amplitude (max-min). Is anyone knowing if this package can provide this kind of data? I appreciate.

On Elena Menéndez's question above, is there an answer. I am finding that amplitude is half the range as well in this method.? Anyone knows why?

"I have noticed one important difference in the rainflow when compared with the rutine used by the software Bladed. The latter always assigns one full cycle to the range (max-min) of the timeseries. However, your rutine assigns 0.5 cycles to this range. Which one is more accurate? "

I found out that my first error came from a conflict caused by a similar filename and function name (Rainflow.m/rainflow) But now my error is:
??? Undefined function or method 'rainflow' for input arguments of type
'double'.

Error in ==> testinterpolasjon at 19
rf = rainflow(ext,exttime);

I'm running Matlab release 2009a

I can't get this working. I try the rfdemo1 using the syntax found in the rfdemo1.m, f.ex.
rfdemo1([2 3 2 4 2 5 1 6])

My error output is
>> rfdemo1([2 3 2 4 2 5 1 6])
??? Attempt to execute SCRIPT rainflow as a function:
C:\Users\Andreas\Documents\MATLAB\Rainflow cycle counting\rainflow.m

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

Anyone know why?
