17

This PR resolves issue #610 by adding a new config variable to reset the already-calculated pearson value to `1.0` when it exceeds the threshold set by the config variable.

Add STIMP (Pan Matrix Profile) Tutorial

10

An initial tutorial has already been created [here](https://github.com/TDAmeritrade/stumpy/blob/main/docs/Tutorial_Pan_Matrix_Profile.ipynb) We need to add a final example where there are [two different window sizes within the same dataset](https://arxiv.org/pdf/1802.04883.pdf). The data can be...

Handle Constant Regions Consistently

16

Currently, `stumpy.stump` and `stumpy.stumped` can account for constant regions. So, when two subsequences are being compared and one subsequence is constant (and the second is not constant) then the pearson...

Allow user to use pre-calculated `mp` in `stumpy.stumpi.py`

1

It seems that `stumpy.stumpi.py` needs to calculate `matrix profile (mp)` in the beginning of the algorithm. https://github.com/TDAmeritrade/stumpy/blob/576de379994896063be71d264e48a08ae17476cf/stumpy/stumpi.py#L118 And, then it will be updated quickly for each new individual, scaler value...
