Experimenting with Lapped Transforms

A Jupyter Notebook for experimenting with lapped transforms.

Click the following links to open the notebooks in Jupyter nbviewer (some math is broken when you open these files directly on GitHub):

1. Analysing Lapped Transforms
2. Transforming Lapped Signal Vectors

Motivation and Theory, see
