Classes

valarray	numeric arrays and array slices (class template)
slice	BLAS-like slice of a valarray: starting index, length, stride (class)
slice_array	proxy to a subset of a valarray after applying a slice (class template)
gslice	generalized slice of a valarray: starting index, set of lengths, set of strides (class)
gslice_array	proxy to a subset of a valarray after applying a gslice (class template)
mask_array	proxy to a subset of a valarray after applying a boolean mask operator[] (class template)
indirect_array	proxy to a subset of a valarray after applying indirect operator[] (class template)
