spectrochempy.polynomialbaseline
- class polynomialbaseline[source]
Arbitrary-degree polynomial (degree limited to 10, however).
As a linear baseline is automatically calculated, this polynom is always of greater or equal to order 2 (parabolic function).
\[f(x) = ampl * \sum_{i=2}^{max} c_i*x^i\]Attributes Summary
