# Fit Sum of Exponentials

The [files](./docs/files) directory contains a collection of **Python** scripts that implement the method proposed in this [stackexchange answer](https://math.stackexchange.com/questions/1428566/fit-sum-of-exponentials/3808325#3808325) to fit data to a sum of exponentials with an arbitrary number of exponential terms.

This repo also contains a static [jupyterlite](https://jupyterlite.readthedocs.io) website with a custom [pyodide](https://pyodide.org) kernel and the [PyArma](https://pyarma.sourceforge.io) Python module compiled for [webassembly](https://webassembly.org).

The website available at [**juangburgos.github.io/FitSumExponentials**](http://juangburgos.github.io/FitSumExponentials) allows to run the Python scripts in an _interactive_ Python environment that requires zero installation and no backend server, and it runs in almost all modern web browsers and devices.

Kudos to the _jupyterlite_, _pyodide_ and _PyArma_ guys for making this possible.

## Old Matlab Code

Before using Python and PyArma for exponentials the fit method implementation, there was a Matlab version, which was was available in an interactive online environment provided by [OctaveOnline](https://octave-online.net). Sadly, OctaveOnline decided to delete all my saved and shared scripts without any notification, which motivated me to create this static wbesite.

The old Matlab scripts can be accessed in the [matlab](./matlab) directory.
