operator*()

Vec3D operator*	(	const MatrixSymmetric3D &	A,
		const Vec3D &	b
	)

Multiplication of a symmetric 3D matrix with a vector (global operator, friend of this class)

Parameters

[in]	A	the matrix
[in]	b	the vector

Returns

The multiplication result

{
    return Vec3D(A.XX * b.X + A.XY * b.Y + A.XZ * b.Z,
                 A.XY * b.X + A.YY * b.Y + A.YZ * b.Z,
                 A.XZ * b.X + A.YZ * b.Y + A.ZZ * b.Z);
}

operator<<()

std::ostream& operator<<	(	std::ostream &	os,
		const MatrixSymmetric3D &	A
	)

Adds all elements of a symmetric 3D matrix to an ostream

Parameters

[in,out]	os	output stream
[in]	A	the matrix

Returns

(reference to) output stream with matrix elements added

{
    os << A.XX << ' ' << A.XY << ' ' << A.XZ << " " << A.YY << ' ' << A.YZ << " " << A.ZZ;
    return os;
}

operator>>()

std::istream& operator>>	(	std::istream &	is,
		MatrixSymmetric3D &	A
	)

Reads the elements of a symmetric 3D matrix from an istream

Parameters

[in,out]	is	input stream,
[out]	A	the matrix

Returns

(reference to) input stream from with matrix elements were read

{
    is >> A.XX >> A.XY >> A.XZ >> A.YY >> A.YZ >> A.ZZ;
    return is;
}
