trapezoid(dataset, **kwargs)[source]๏ƒ

Integrate using the composite trapezoidal rule.

Wrapper of scipy.integrate.trapezoid.

Performs the integration along the last or given dimension.

Parameters:

  • dataset (NDDataset) โ€“ Dataset to be integrated.

  • **kwargs โ€“ Additional keywords parameters. See Other Parameters.

Returns:

NDDataset โ€“ Definite integral as approximated by trapezoidal rule.

Other Parameters:

dim (int or str, optional, default: "x") โ€“ Dimension along which to integrate. If an integer is provided, it is equivalent to the numpy axis parameter for numpy.ndarray.
