Classes

gslice Class

A utility class to valarray that is used to define multi-dimensional slices of a valarray.

gslice_array Class

An internal, auxiliary template class that supports general slice objects by providing operations between subset arrays defined by the general slice of a valarray.

indirect_array Class

An internal, auxiliary template class that supports objects that are subsets of valarrays by providing operations between subset arrays defined by specifying a subset of indices of a parent valarray.

mask_array Class

An internal, auxiliary template class that supports objects that are subsets of parent valarrays, specified with a Boolean expression, by providing operations between the subset arrays.

slice Class

A utility class to valarray that is used to define one-dimensional, vector-like subsets of a valarray.

slice_array Class

An internal, auxiliary template class that supports slice objects by providing operations between subset arrays defined by the slice of a valarray.

valarray Class

The template class describes an object that controls a sequence of elements of type Type that are stored as an array and designed for performing high-speed mathematical operations, optimized for computational performance.

Specializations
