Struct bevy_rapier2d::prelude::nalgebra::linalg::givens::GivensRotation [−][src]
pub struct GivensRotation<T> where
T: ComplexField, { /* fields omitted */ }
Expand description
A Givens rotation.
Implementations
The Givents rotation that does nothing.
Initializes a Givens rotation from its components.
The components are copies as-is. It is not checked whether they describe an actually valid Givens rotation.
Initializes a Givens rotation from its non-normalized cosine an sine components.

c: T,
s: T,
eps: <T as ComplexField>::RealField
) -> Option<(GivensRotation<T>, T)>
[src]
pub fn try_new(
c: T,
s: T,
eps: <T as ComplexField>::RealField
) -> Option<(GivensRotation<T>, T)>
[src]Initializes a Givens rotation form its non-normalized cosine an sine components.
Computes the rotation R
required such that the y
component of R * v
is zero.
Returns None
if no rotation is needed (i.e. if v.y == 0
). Otherwise, this returns the norm
of v
and the rotation r
such that R * v = [ |v|, 0.0 ]^t
where |v|
is the norm of v
.
Computes the rotation R
required such that the x
component of R * v
is zero.
Returns None
if no rotation is needed (i.e. if v.x == 0
). Otherwise, this returns the norm
of v
and the rotation r
such that R * v = [ 0.0, |v| ]^t
where |v|
is the norm of v
.
The cos part of this roration.
The inverse of this givens rotation.
