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 [1]. Note that MyVoldKalman2.m was also published in a Matlab conference paper. However, the M-code for the simultaneous, multi-order implementation [2] 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 [2] 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 [1]. 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 publications. 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. References: [1] J.
