class ams.core.service.VarReduction(u: Callable, fun: Callable, name: str = None, tex_name: str = None, unit: str = None, info: str = None, vtype: Type = None, rfun: Callable = None, rargs: dict = None, no_parse: bool = False, sparse: bool = False)

A numerical matrix to reduce a 2D variable to 1D, np.fun(shape=(1, u.n)).

Parameters:

uCallable

The input matrix variable.

funCallable

The reduction function that takes a shape argument (1D shape) as input.

namestr, optional

The name of the instance.

tex_namestr, optional

The TeX name for the instance.

unitstr, optional

The unit of the output.

infostr, optional

A description of the operation.

vtypeType, optional

The variable type.

rfunCallable, optional

Function to apply to the output of fun.

rargsdict, optional

Keyword arguments to pass to rfun.

no_parse: bool, optional

True to skip parsing the service.

sparse: bool, optional

True to return output as scipy csr_matrix.
