spectrochempy.Quantity

class Quantity(value, units=None)

Methods

Quantity.check(dimension)	Return true if the quantity's dimension matches passed dimension.
Quantity.compute(**kwargs)	Compute the Dask array wrapped by pint.PlainQuantity.
Quantity.dot(b)	Dot product of two arrays.
Quantity.from_list(quant_list[, units])	Transforms a list of Quantities into an numpy.array quantity.
Quantity.from_sequence(cls, seq[, units])	Transforms a sequence of Quantities into an numpy.array quantity.
Quantity.is_compatible_with(self, other, ...)	check if the other object is compatible
Quantity.ito([other])	Inplace rescale to different units.
Quantity.ito_base_units()	Return PlainQuantity rescaled to plain units.
Quantity.ito_reduced_units()	Return PlainQuantity scaled in place to reduced units, i.e. one unit per dimension.
Quantity.ito_root_units()	Return PlainQuantity rescaled to root units.
Quantity.m_as(units)	PlainQuantity's magnitude expressed in particular units.
Quantity.persist(**kwargs)	Persist the Dask Array wrapped by pint.PlainQuantity.
Quantity.prod(_prod_dispatcher)def prod(a[, ...])	Return the product of quantity elements over a given axis
Quantity.to([other])	Return PlainQuantity rescaled to different units.
Quantity.to_base_units()	Return PlainQuantity rescaled to plain units.
Quantity.to_compact([unit])	"Return PlainQuantity rescaled to compact, human-readable units.
Quantity.to_reduced_units()	Return PlainQuantity scaled in place to reduced units, i.e. one unit per dimension.
Quantity.to_root_units()	Return PlainQuantity rescaled to root units.
Quantity.visualize(**kwargs)	Produce a visual representation of the Dask graph.
