Implementation of a rotation vector as Euler angle minimal representation.
Class that consider the case of the Euler angles using the z-y-z convention, where are respectively the rotation angles around the , and axis.
with
The rotation matrix corresponding to the z-y-z convention is given by:
The vpRzyzVector class is derived from vpRotationVector.
From the implementation point of view, it is nothing more than an array of three doubles with values in [rad].
You can set values [rad] accessing each element:
You can also initialize the vector using operator<<(double):
Or you can also initialize the vector from a list of doubles if ViSP is build with c++11 enabled:
To get the values [rad] use:
The code below shows first how to initialize this representation of Euler angles, than how to contruct a rotation matrix from a vpRzyzVector and finally how to extract the vpRzyzVector Euler angles from the build rotation matrix.

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 :
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:
vpException::incorrectMatrixSizeError | if the sizes of the matrices do not allow the operations. |
A | : An array that could be a vpMatrix. |
B | : An array that could be a vpMatrix. |
alpha | : A scalar. |

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. |
