Type Definition nalgebra::base::Matrix1

pub type Matrix1<T> = Matrix<T, U1, U1, ArrayStorage<T, 1, 1>>;

A stack-allocated, column-major, 1x1 square matrix.

Because this is an alias, not all its methods are listed here. See the Matrix type too.

Implementations

impl<T> Matrix1<T>

pub fn into_scalar(self) -> T

Convert this 1x1 matrix into a scalar.

As opposed to indexing, using this provides type-safety when flattening dimensions.

Example

let v = Vector3::new(0., 0., 1.);
let inner_product: f32 = (v.transpose() * v).into_scalar();
assert_eq!(inner_product, 1.);

 let v = Vector3::new(0., 0., 1.);
 let mut inner_product: f32 = (v * v.transpose()).into_scalar();
