Detailed Description

Class that consider the case of a translation vector.

Let us denote $^{a}{\bf t}_{b} = [t_x,t_y,t_z]^\top$ the translation from frame $ a $ to frame $ b $. The representation of a translation is a column vector of dimension 3.

Translations along x,y,z axis are expressed in meters.

From the implementation point of view, it is nothing more than an array of three doubles with values in [meters].

You can set values [meters] accessing each element:

vpTranslationVector t;
t[0] = 0;
t[1] = 0.1;
t[2] = 0.5;

You can also initialize the vector using operator<<(double):

t << 0, 0.1, 05;

Or you can also initialize the vector from a list of doubles if ViSP is build with c++11 enabled:

#if (VISP_CXX_STANDARD >= VISP_CXX_STANDARD_11)
t = {0, 0.1, 0.5};
#endif

To get the values [meters] use:

double tx = t[0];
double ty = t[1];
double tz = t[2];

The code below shows how to use a translation vector to build an homogeneous matrix.

#include <visp3/core/vpHomogeneousMatrix.h>
#include <visp3/core/vpRotationMatrix.h>
#include <visp3/core/vpTranslationVector.h>
int main()
{
vpTranslationVector t; // Translation vector
// Initialization of the translation vector
t[0] = 0.2; // tx = 0.2 meters
t[1] = -0.1; // ty = -0.1 meters
t[2] = 1.0; // tz = 1 meters
// Construction of a rotation matrix
vpRotationMatrix R; // Set to identity by default
// Construction of an homogeneous matrix
vpHomogeneousMatrix M(t, R);
}

)
related

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);

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::incorrectMatrixSizeErrorif 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.
