operator*=() [2/2]

std::enable_if< is_rng<val_t>::value && std::is_convertible<elem_t, val_t>::value , typename Matrix<val_t, alloc_t, der_t, policy_t>::derived_type& >::type Chusov::Math::operator*=	(	Matrix< val_t, alloc_t, der_t, policy_t > &	left,
		elem_t &&	val
	)

Multiplies a matrix and a scalar and assigns the product to the matrix.

Template Parameters

val_t	is a type of an element of the matrix.
alloc_t	is a type of an allocator used by the left matrix.
der_t	is a derived type of the first operand. See Matrix::derived_type.
policy_t	is an execution policy of the matrix.
elem_t	is a type of the scalar multiplied to the matrix.

Parameters

left	is an lvalue reference to the matrix to which the right operand is multiplied and to which the product is assigned.
val	is a universal reference to the scalar to be multiplied to the matrix from the right.

Returns

Returns a reference to left cast to the

typename Matrix<val1_t, alloc1_t, der1_t, policy1_t>::derived_type

after the multiplication has been performed.

Remarks

The operation is defined only when elements of the matrix appertain to an Rng, and values of the elem_t type are convertible to val1_t.
