void	GetAsArray (float *out_pData, plMatrixLayout::Enum layout) const
void	Transpose ()
	Transposes this matrix.
plSimdMat4f	GetTranspose () const
	Returns the transpose of this matrix.
plResult	Invert (const plSimdFloat &fEpsilon=plMath::SmallEpsilon< float >())
	Inverts this matrix. Return value indicates whether the matrix could be inverted.
plSimdMat4f	GetInverse (const plSimdFloat &fEpsilon=plMath::SmallEpsilon< float >()) const
	Returns the inverse of this matrix.
bool	IsEqual (const plSimdMat4f &rhs, const plSimdFloat &fEpsilon) const
	Equality Check with epsilon.
bool	IsIdentity (const plSimdFloat &fEpsilon=plMath::DefaultEpsilon< float >()) 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.

plSimdVec4f	TransformPosition (const plSimdVec4f &v) const
	Matrix-vector multiplication, assuming the 4th component of the vector is one (default behavior).
plSimdVec4f	TransformDirection (const plSimdVec4f &v) const
	Matrix-vector multiplication, assuming the 4th component of the vector is zero. So, rotation/scaling only.

void	operator*= (const plSimdMat4f &rhs)
