nwtc_num::skewsymmat Interface Reference

This function returns the 3x3 skew-symmetric matrix for cross-product calculation of vector \(\vec{x}\) via matrix multiplication, defined as

\begin{equation} f_{_\times}\left( \vec{x} \right) = \begin{bmatrix} 0 & -x_3 & x_2 \\ x_3 & 0 & -x_1 \\ -x_2 & x_1 & 0 \end{bmatrix} \end{equation}

Use SkewSymMat (nwtc_num::skewsymmat) instead of directly calling a specific routine in the generic interface. More...
