to_skew_symmetric Function

public pure function to_skew_symmetric(x) result(rst)

Converts a 3-element vector to a 3-by-3 skew-symmetric matrix. A skew-symmetric matrix is defined as follows.

$$\tilde{x} = \left[ \begin{matrix} 0 & -x_{3} & x_{2} \\ x_{3} & 0 & -x_{1} \\ -x_{2} & x_{1} & 0 \end{matrix} \right]$$

Arguments

Type	Intent	Optional	Attributes		Name
real(kind=real64),	intent(in)			::	x(3)	The vector.

Return Value real(kind=real64), (3,3)
