◆ svx() [1/2]

static void svx ( const Eigen::MatrixBase< Vector3 > &  v,
const Symmetric3Tpl< _Scalar, _Options > &  S3,
const Eigen::MatrixBase< Matrix3 > &  M 
)
inlinestatic

Performs the operation \( M = S_{3} [v]_{\times} \).

Template Parameters
Vector3,Matrix3
Parameters
[in]va vector of dimension 3.
[in]S3a symmetric matrix of dimension 3x3.
[out]Man output matrix of dimension 3x3.

Definition at line 285 of file symmetric3.hpp.

◆ svx() [2/2]

Matrix3 svx ( const Eigen::MatrixBase< Vector3 > &  v) const
inline
