# Adaptive Curvefitting Tool
[](https://badge.fury.io/py/adaptive-curvefitting)
[](https://pepy.tech/project/adaptive-curvefitting)
[](https://doi.org/10.5281/zenodo.3893596)
Adaptive curvefitting is a tool to find potentially optimal models for your research data. It's based on [scipy], [numpy], and [matplotlib].

## Why is this tool
The very difference of adaptive-curvefitting with [numpy.polyfit], [scipy.optimize.curve_fit] or [scipy.optimize.least_squares] is ***the hypothesis you don’t know which model to fit***. If you already have the expected model, the methods in [scipy] and [numpy] are fantastic tools and better than this one. ***When you explore something unknown, this will be a maybe***.
## Installation, update and uninstallation
### To install
Quick installation with [pip]:
```bash
pip install adaptive-curvefitting
```
Or from github:
```bash
pip install git+https://github.com/longavailable/adaptive-curvefitting
```
### To update
```bash
pip install --upgrade adaptive-curvefitting
```
### To uninstall
```bash
pip uninstall adaptive-curvefitting
```
## Usage
### Import the required module
In general,
```python
import longscurvefitting
```
or import the specified function:
```python
from longscurvefitting import oneClickCurveFitting
from longscurvefitting import generateFunction
from longscurvefitting import generateModels
```
### Do the curvefitting
```python
oneClickCurveFitting(xdata, ydata)
```
There are some optional arguments of `oneClickCurveFitting`.
- functions: specified or all (default) basic models(name of models) to fit.
- Type: list of string
- Default: basicModels_nameList
- piecewise: if consider custom a piecewise function. It is mandatory not to 'piecewise' when the data size is less than 20.
- Type: bool
- Default: False
- operator: operatation between basic models.
- Type: string
- Default: '+'
- maxCombination: max number of combination of basic models.
- Type: integer
- Default: 2
- plot_opt: the number of plot for optimal models.
- Type: integer
- Default: 10
- xscale: one of {"linear", "log", "symlog", "logit", ...}
- Type: string
- Default: None
- yscale: one of {"linear", "log", "symlog", "logit", ...}
- Type: string
- Default: None
- filename_startwith: a custom string mark as part of output filename
- Type: string
- Default: 'curvefit'
- silent: minimal output to monitor
- Type: boolean
- Default: False
- feedback: if True, return the optimal model(function object), parameters
- Type: boolean
- Default: False
- kwargs: keyword arguments passed to `curve_fit_m`. Note that `bounds` and `p0` will take no effect when multi-models.
- Type: dict
See the complete example "[/tests/curvefitting.py]".
### Generate a expected model
Create a model composited by gaussian and erf function:
```python
funcs = ['gaussian','erf']
myfunc = generateFunction(funcs, functionName='myfunc', operator='+')['model']
```
See the complete example "[/tests/custom_a_model.py]".
### Re-use the fitted curve
See the complete example "[/tests/reuse_the_fitted_model.py]".
## Shortages
- Based on [scipy.optimize.least_squares], it cannot enhance the estimate of specified model. Evenmore, it has more limit than [scipy.optimize.least_squares].
For example, arguments of `bounds`, `x0` or `p0` were not supported due to the ***basic hypothesis***.
