add()

template<typename ElementType , int DIM>

static void FEVV::Math::Matrix::Square::add ( const ElementType  p_matrix[][DIM], ElementType  p_matrix_sum[][DIM]  )

static

add two matrices

Here is the caller graph for this function:

covar() [1/2]

template<typename CoordinateType , size_t N>

static std::vector< CoordinateType > FEVV::Math::Matrix::Square::covar ( const CoordinateType  point_coords[3 *N] )

static

Compute the 3 x 3 covariance matrix of N 3D points that are stored into a one-dimensional array pointCoords [P1x, P1y, P1z, ..., PNx, PNy, PNz].

Definition at line 909 of file MatrixOperations.hpp.

covar() [2/2]

template<typename CoordinateType >

static std::vector< CoordinateType > FEVV::Math::Matrix::Square::covar ( const std::vector< CoordinateType > &  point_coords )

static

Compute the 3 x 3 covariance matrix of N 3D points that are stored into a one-dimensional std::vector [P1x, P1y, P1z, ..., PNx, PNy, PNz].

is_diagonal()

template<typename ElementType , int DIM>

static bool FEVV::Math::Matrix::Square::is_diagonal ( const ElementType  p_matrix[DIM][DIM] )

static

Definition at line 1048 of file MatrixOperations.hpp.

Here is the call graph for this function:

transformation() [1/2]

template<typename ElementType , int DIM = 3>

static void FEVV::Math::Matrix::Square::transformation ( const ElementType  pp_matrix[DIM][DIM], const ElementType  in_vertex[DIM], ElementType  out_vertex[DIM]  )

static

Compute the matrix tranformation of a vector. Use can use it to rotate, scale or even translate your vertex (in the later case homogeneous coordinates should be used).

Parameters

in_vertex	represent our square matrix that contains the transformation.
out_vertex	represent the one dimensional untransformed column vertex represent the one dimensional transformed column vertex

Definition at line 991 of file MatrixOperations.hpp.

transformation() [2/2]

template<typename ElementType , int DIM, int N>

static void FEVV::Math::Matrix::Square::transformation ( const ElementType  pp_matrix[DIM][DIM], const ElementType  in_vertices[DIM][N], ElementType  out_vertices[DIM][N]  )

static

Compute the matrix tranformation of N vectors [V1 V2 V3 ... VN] (column-vectors). Use can use it to rotate, scale or even translate your vertex (in the later case homogeneous coordinates should be used).

Parameters

in_vertices	represent our square matrix that contains the transformation.
out_vertices	represent the untransformed column vertices represent the transformed column vertices

Definition at line 1014 of file MatrixOperations.hpp.

template<typename ElementType , int DIM = 3>

static void FEVV::Math::Matrix::Square::vector_times_transpose_mult ( const ElementType *  p_vector, ElementType  pp_matrix[][DIM], ElementType  coeff  )

static

Compute coef * V x V^t (V is a vertical DIM-D vector)
