# rnd-pcw-poly
Generates random piecewise polynomial functions (for example for testing CPD-algorithms).
## Example
```python
import numpy as np
import matplotlib.pyplot as plt
from rnd_pcw_poly import rnd_pcw_poly
# generate a piecewise polynomial function with 5 "jumps" / 6 segments;
# no more than 200 degrees of freedom in total and locally no more than
# 6 degrees of freedom.
p = rnd_pcw_poly(5, 200, 6)
# plot it
xs = np.linspace(0,1,5000)
ys = p(xs)
plt.scatter(xs, ys)
plt.show()
```
The algorithm has seperately seedable and idependent core characteristics like jump locations, dof distribution, realization etc.
