# AdAdjust

Package allowing to fit any mathematical function to (for now 1-D only) data.

## Installation

```bash

pip install adadjust

```

## Usage

```python

from adadjust import Function

import numpy as np

import matplotlib.pyplot as plt

plt.rcParams.update({"text.usetex": True})  # Needs texlive installed

nsamples = 1000

a = 0.3

b = -10

xstart = 0

xend = 1

noise = 0.01

x = np.linspace(xstart, xend, nsamples)

y = a * x ** 2 + b + np.random.normal(0, noise, nsamples)

def linfunc(xx, p):

    return xx * p[0] + p[1]

def square(xx, p):

    return xx ** 2 * p[0] + p[1]

func = Function(linfunc, "$a \\times p[0] + p[1]$")

func2 = Function(square, "$a^2 \\times p[0] + p[1]$")

params = func.fit(x, y, np.array([0, 0]))[0]

rr = func.compute_rsquared(x, y, params)

params2 = func2.fit(x, y, np.array([0, 0]))[0]

rr2 = func2.compute_rsquared(x, y, params2)

table = Function.make_table(

    [func, func2], [params, params2], [rr, rr2], caption="Linear and Square fit", path_output="table.pdf"

)

table.compile()

Function.plot(x, [func, func2], [params, params2], y=y, rsquared=[rr, rr2])

plt.gcf().savefig("plot.pdf")

```

**NOTE** : to have pretty gaphs, put the line `plt.rcParams.update({"text.usetex": True})` just after you imported adadjust.

This requiers that you have TexLive full installed on your computer.

The result will be :
