spectrochempy.trapz

trapz(*args, **kwargs)

An alias of trapezoid kept for backwards compatibility.

Integrate using the composite trapezoidal rule.

Wrapper of scpy.integrate.trapezoid.

Performs the integration along the last or given dimension.

datasetNDDataset

Dataset to be integrated.

**kwargs

Additional keywords parameters. See Other Parameters.

integral
