`pub fn tilde_matrix(v: &Vector3<f64>) -> Matrix3<f64>`

## Expand description

Returns the skew-symmetric matrix (also known as the tilde matrix) corresponding to the provided 3D vector.

The skew-symmetric matrix of a vector `v`

is defined as:

```
0 -v.z v.y
v.z 0 -v.x
-v.y v.x 0
```

This matrix has the property that for any vector `w`

, the cross product `v x w`

can be computed as the matrix product of the skew-symmetric matrix of `v`

and `w`

.
