Functions
bool	gtsam::fpEqual (double a, double b, double tol, bool check_relative_also=true)
	Ensure we are not including a different version of Eigen in user code than while compiling gtsam, since it can lead to hard-to-understand runtime crashes.
void	gtsam::print (const Vector &v, const std::string &s, std::ostream &stream)
	print without optional string, must specify cout yourself
void	gtsam::print (const Vector &v, const std::string &s="")
	print with optional string to cout
void	gtsam::save (const Vector &A, const std::string &s, const std::string &filename)
	save a vector to file, which can be loaded by matlab
bool	gtsam::equal_with_abs_tol (const Vector &vec1, const Vector &vec2, double tol=1e-9)
	VecA == VecB up to tolerance.
bool	gtsam::equal_with_abs_tol (const SubVector &vec1, const SubVector &vec2, double tol)
bool	gtsam::equal (const Vector &vec1, const Vector &vec2, double tol)
	Override of equal in Lie.h.
bool	gtsam::equal (const Vector &vec1, const Vector &vec2)
	Override of equal in Lie.h.
bool	gtsam::assert_equal (const Vector &vec1, const Vector &vec2, double tol=1e-9)
	Same, prints if error.
bool	gtsam::assert_inequal (const Vector &vec1, const Vector &vec2, double tol=1e-9)
	Not the same, prints if error.
bool	gtsam::assert_equal (const SubVector &vec1, const SubVector &vec2, double tol=1e-9)
	Same, prints if error.
bool	gtsam::assert_equal (const ConstSubVector &expected, const ConstSubVector &actual, double tol)
bool	gtsam::linear_dependent (const Vector &vec1, const Vector &vec2, double tol=1e-9)
	check whether two vectors are linearly dependent
Vector	gtsam::ediv_ (const Vector &a, const Vector &b)
	elementwise division, but 0/0 = 0, not inf
template<class V1, class V2>
double	gtsam::dot (const V1 &a, const V2 &b)
	Dot product.
pair< double, Vector >	gtsam::house (const Vector &x)
	house(x,j) computes HouseHolder vector v and scaling factor beta from x, such that the corresponding Householder reflection zeroes out all but x.
double	gtsam::houseInPlace (Vector &x)
	beta = house(x) computes the HouseHolder vector in place
pair< Vector, double >	gtsam::weightedPseudoinverse (const Vector &v, const Vector &weights)
	Weighted Householder solution vector, a.k.a., the pseudoinverse of the column NOTE: if any sigmas are zero (indicating a constraint) the pseudoinverse will be a selection vector, and the variance will be zero.
double	gtsam::weightedPseudoinverse (const Vector &a, const Vector &weights, Vector &pseudo)
Vector	gtsam::concatVectors (const std::list< Vector > &vs)
	concatenate Vectors
