 Global functions in a separate testing namespace.
 

Functions

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::operator== (const Vector &vec1, const Vector &vec2)
 operator==()
 
bool gtsam::greaterThanOrEqual (const Vector &v1, const Vector &v2)
 Greater than or equal to operation returns true if all elements in v1 are greater than corresponding elements in v2.
 
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::assert_equal (const Vector &vec1, const Vector &vec2, double tol=1e-9)
 Same, prints if error. More...
 
bool gtsam::assert_inequal (const Vector &vec1, const Vector &vec2, double tol=1e-9)
 Not the same, prints if error. More...
 
bool gtsam::assert_equal (const SubVector &vec1, const SubVector &vec2, double tol=1e-9)
 Same, prints if error. More...
 
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 More...
 
Vector gtsam::ediv_ (const Vector &a, const Vector &b)
 elementwise division, but 0/0 = 0, not inf More...
 
double gtsam::houseInPlace (Vector &x)
 beta = house(x) computes the HouseHolder vector in place
 
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. More...
 
double gtsam::weightedPseudoinverse (const Vector &a, const Vector &weights, Vector &pseudo)
 
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. More...
 
Vector gtsam::concatVectors (const std::list< Vector > &vs)
 concatenate Vectors
 
Vector gtsam::concatVectors (size_t nrVectors,...)
 concatenate Vectors
