**Is your feature request related to a problem? Please describe.** Make `PyDynamic.uncertainty.interpolate.interp1d_unc` allow also for the additional interpolation modes `0,1,2,3,"slinear", "quadratic"` from `scipy.interpolate.interp1d`. **Describe the solution you'd like** This should...

**Is your feature request related to a problem? Please describe.** The spline interpolation at its current state has "edges" at the boundaries, if extrapolation becomes necessary. This is in line...

Currently, [FIRuncFilter](https://github.com/PTB-PSt1/PyDynamic/blob/master/PyDynamic/uncertainty/propagate_filter.py#L42) allows to hand over a low-pass `blow` to pre-filter the signal before the actual FIR-application. This is in line with the underlying paper. Because `blow` is just a...

Element-wise multiplication (Hadamar product) is a useful operation to enable applications like "windowing" and "gating" of signals in the time and frequency domain. Two new functions are introduced with this...

Add comparison against known example for Hadamar product

This PR fixes issue #331 and implements the trust anchor for the Hadamar product method.

This PR defines a variable "`custom_atol=100*machine_epsilon`" in the `conftest.py` and uses it in all assert_allclose statements, that did not already declare a (larger) absolute tolerance previously. Motivation: `numpy.testing.assert_allclose` uses default...
