nda::expr_unary< OP, A >

#include <nda/arithmetic.hpp>

Detailed Description

template<char OP, Array A>
struct nda::expr_unary< OP, A >

Lazy unary expression for nda::Array types.

A lazy unary expression contains a single operand and a unary operation. It fulfills the nda::Array concept and can therefore be used in any other expression or function that expects an nda::Array type.

The only supported unary operation is the negation operation ('-').

Template Parameters

OP	Char representing the unary operation.

Parameters

A	nda::Array type.

Member Function Documentation

operator()()

template<char OP, Array A>

template<typename... Args>

auto nda::expr_unary< OP, A >::operator() ( Args &&... args ) const

inline

Function call operator.

Forwards the arguments to the nda::Array operand and negates the result.

Template Parameters

Args	Types of the arguments.

Parameters

args	Function call arguments.

Returns

If the result of the forwarded function call is another nda::Array, a new lazy expression is returned. Otherwise the result is negated and returned.

Definition at line 66 of file arithmetic.hpp.

shape()

template<char OP, Array A>

auto nda::expr_unary< OP, A >::shape ( ) const

inlinenodiscardconstexpr

Get the shape of the nda::Array operand.

Returns

std::array<long, Rank> object specifying the shape of the operand.

Definition at line 74 of file arithmetic.hpp.

size()

template<char OP, Array A>

long nda::expr_unary< OP, A >::size ( ) const

inlinenodiscardconstexpr

Get the total size of the nda::Array operand.

Returns

Number of elements contained in the operand.
