	Transposes this matrix.
ezSimdMat4d	GetTranspose () const
	Returns the transpose of this matrix.
ezResult	Invert (const ezSimdDouble &fEpsilon=ezMath::SmallEpsilon< double >())
	Inverts this matrix. Return value indicates whether the matrix could be inverted.

	Returns the inverse of this matrix.
bool	IsEqual (const ezSimdMat4d &rhs, const ezSimdDouble &fEpsilon) const
	Equality Check with epsilon.
bool	IsIdentity (const ezSimdDouble &fEpsilon=ezMath::DefaultEpsilon< double >()) const
	Checks whether this is an identity matrix.
bool	IsValid () const
	Checks whether all components are finite numbers.
bool	IsNaN () const
	Checks whether any component is NaN.

	Matrix-vector multiplication, assuming the 4th component of the vector is one (default behavior).
ezSimdVec4d	TransformDirection (const ezSimdVec4d &v) const
	Matrix-vector multiplication, assuming the 4th component of the vector is zero. So, rotation/scaling only.
