A 1-D Specialization of the Array class.
Matrix< T > matrix() const
Convert the SquareMatrix to a Matrix.
SquareMatrix()
Default constructor - creates a unity matrix at present, this may not be what we want (non-intuitive...
SquareMatrix< T, n > & operator*=(const SquareMatrix< T, n > &other)
Matrix product of 'this' SquareMatrix with other, i.e., A*=B; is equivalent with A=A*B where '*' is m...
SquareMatrix< T, n > & adjoint()
Tranpose and conjugate the matrix in place(!).
~SquareMatrix()
Destructor.
SquareMatrix< T, n > & operator=(const T a[n][n])
Assign a c-style matrix, creates a general matrix.
T operator()(Int i, Int j) const
Indexing, only const indexing is allowed.
A 2-D Specialization of the Array class.
SquareMatrix(const Vector< T > &vec)
Construct from Vector, creates a diagonal matrix.
