Hi,
I have two columns of data that I'm generating in OriginC which are also stored as vectors. I would like to find the correlation and lag from this data using the LabTalk function fft.corr().
In origin c I have tried using:
LT_execute("fft.corr(col(ParaPhotons),col(SysResln));col(correlation)=fft.corr.corrData$;");
but it doesn't do anything... IU don't think it's even executing the correlation function... If I enter
type -b "my msg";
in between the statements that seems to work... I just can't get it to correlate the data.
Thanks in advance |

1. fft.corr() automatically fills the dataset named by fft.corr.corrData$.
2. Column names are not sufficient as arguments or values... full dataset names are required.
If the columns are in the active worksheet then this will work...
LT_execute("fft.corr.corrData$=%H_correlation; fft.corr(%H_ParaPhotons,%H_SysResln)");
