Matlab 7 R14 function "red2"?

I'm trying to modify some old Matlab m-files (which someone else created) from version 7 R14 to work with R2013a. I've come across a function that I can't find in the Matlab 2013a Help, or by an internet search. At this point, I'm just trying to figure out if the function was a built-in Matlab function, or if it was created by the original author of the m-files.

The name of the function is "red2", and here are the two cases in the m-files where I have found the function used:

1) v(:,1)=red2(x(:,r),'anom',anom); v(:,2)=red2(y(:,r),'anom',anom); v(:,3)=red2(z(:,r),'anom',anom); %x, y, and z are simulated time series %anom was set = to 0, and was commented "%seasonal de-trend, anom = number of season"

2) v(:,1)=red2(x(:,r),'anom',anom(1),'pad','y'); v(:,2)=red2(y(:,r2),'anom',anom(2),'pad','y'); %anom was set = to [0 0], and was commented "%remove periodicity anom"

I can tell from this info that "red2" was a kind of normalization/detrending function, but that's all I know.

Can anyone tell me if "red2" was a built-in function in Matlab version 7 R14 (or other past versions)? If so, can you post any documentation? I would really appreciate it.

Thanks, Sam

I don’t recognize ‘ red2 ’ from any MATLAB release in at least the last decade. I suggest you do a search for it either in the file (it could be an anonymous or implicit function) or as a function file ( red2.m ) in the set of files it came from (easy in Windows 7, more difficult in Windows 8).

OK, thanks. I'll email the author of the files to see if it was a function that he created.

My pleasure.

Good luck!
