Detailed Description

Implementation of a generic rotation vector.

Class that consider the case of a generic rotation vector (cannot be used as is !) consisting in three or four angles.

The vpRotationVector class is derived from vpArray2D<double>. The vpRotationVector class is also the base class of specific rotations vectors such as vpThetaUVector, vpRxyzVector, vpRzyxVector, vpRzyzVector and vpQuaternionVector.

The code below shows how this class can be used to manipulate a vpRxyzVector.

#include <iostream>
#include <visp3/core/vpMath.h>
#include <visp3/core/vpRxyzVector.h>
 
int main()
{
  vpRxyzVector r;         // By default initialized to zero
  // Rotation around x set to 45 degres converted in radians
  r[0] = vpMath::rad(45);
  // Rotation around y set to PI radians
  r[1] = M_PI;
  // Rotation around z set to 0 radians
  r[2] = 0;
 
  std::cout << "Rxyz rotation vector: " << r << std::endl;
 
  double rx = r[0];       // Get the value of the angle around x axis
  double ry = r[1];       // Get the value of the angle around y axis
  double rz = r[2];       // Get the value of the angle around z axis
}

Examples: testMatrixInitialization.cpp.

		const double &	alpha,

		const double &	beta,
		vpArray2D< double > &	D,
		const unsigned int &	ops = 0 )

This function performs generalized matrix multiplication: D = alpha*op(A)*op(B) + beta*op(C), where op(X) is X or X^T. Operation on A, B and C matrices is described by enumeration vpGEMMmethod().

For example, to compute D = alpha*A^T*B^T+beta*C we need to call :

vpGEMM(A, B, alpha, C, beta, D, VP_GEMM_A_T + VP_GEMM_B_T);

vpArray2D< double >::vpGEMM

void vpGEMM(const vpArray2D< double > &A, const vpArray2D< double > &B, const double &alpha, const vpArray2D< double > &C, const double &beta, vpArray2D< double > &D, const unsigned int &ops=0)

Definition vpGEMM.h:388

If C is not used, vpGEMM must be called using an empty array null. Thus to compute D = alpha*A^T*B, we have to call:

vpGEMM(A, B, alpha, null, 0, D, VP_GEMM_B_T);

Exceptions

vpException::incorrectMatrixSizeError if the sizes of the matrices do not allow the operations.

Parameters

A	: An array that could be a vpMatrix.
B	: An array that could be a vpMatrix.
alpha	: A scalar.
C	: An array that could be a vpMatrix.
beta	: A scalar.
D	: The resulting array that could be a vpMatrix.
ops	: A scalar describing operation applied on the matrices. Possible values are the one defined in vpGEMMmethod(): VP_GEMM_A_T, VP_GEMM_B_T, VP_GEMM_C_T.
