Vold-Kalman order tracking code (Scripts) Publisher's description

Vold-Kalman second generation, multi-order, simultaneous order tracking code (vkm.m)
Vold-Kalman second generation, multi-order, simultaneous order tracking code (vkm.m).
This method is valid for extracting multiple crossing orders.
Written by Scot McNeill because I got tired of not having access to the V-K method for my
research and decided to program it myself.
Prof. Jiri Tuma has posted m-code for the single-order routine (MyVoldKalman2.m) in publications on
his website . Note that MyVoldKalman2.m was also published in a Matlab conference paper.
However, the M-code for the simultaneous, multi-order implementation  was not posted.
Note that Prof. Tuma posted p-files for all his V-K routines, including simultaneous, multi-order
tracking routine. The P-files didn't work on my vintage of Matlab (2007a), so
I just decided to implement  myself. I provide this first-draft implementation (vkm.m) for other
researchers. M-code is provided.
The additional routine, vk2.m, which does second generation, single-order, noncrossing order tracking
is based on MyVoldKalman2.m . vk2.m is provided as a comparison to vkm.m.
Thanks to Prof. Tuma for making his concise matlab routine (MyVoldKalman2.m) available in his
This implementation has not been rigorously tested and is made available as-is. It is the user's
responsibility to verify output of the routine.
To get started, run the m-files in the demos folder.
