To date there have been no reviews of the time series library posted to the developer or user lists. Is this a bad time for a review, or is no one interested enough in this library to put in the time to submit one? If you feel the library isn't interesting or useful enough, please post a note to the list so I can see that opinion. If you are struggling for time to do the review, please post at least a short opinion, and if a few days extension will make a difference we can investigate that possibility. However, the next review begins on August 13, so time for this is somewhat limited.
I really want to participate but I gave my last exam last week and now I am heading to an Open Source congress for a week. I think I will not have time for a formal review there :(
I have already give Eric feedback a month ago, and I think the library is a nice inclusion for piece wise manipulation series like the ones found in banking account management.
I am not convinced that is the best approach for a general discrete signals framework where to build up digital systems libraries, like FIR and IIR filters, filter networks or non linear and adaptive filters.

Matias, if you summarize your DSP design ideas for the list, then I can tell everyone what I told you ... that a similar design was tried for Time_series and found not to work in practice.
I think that for DSP the best way to model a signal is a dense sequence, that is not based in the RangeRun concepts. I think how to implement convolution or FIR block processing based on DFT and I do not find an easy way, but I have not spend enough time on it.
I asked you to try writing generic algorithms using the concepts you designed. Have you?
No, I have not find the time yet. That is why I just said I am not convinced, no more than that. And I state again that a RangeRun based library is a good addition to Boost and can cohabit in Boost with others DSP libraries. Best regards Matias PS: Sorry for the lenght of the messages, I am in the middle of the congress :)
