Struct nalgebra::linalg::givens::GivensRotation[][src]

pub struct GivensRotation<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.

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 sin part of this roration.

The inverse of this givens rotation.

Performs the multiplication rhs = self * rhs in-place.

Performs the multiplication lhs = lhs * self in-place.

Checks if self is actually part of its subset T (and can be converted to it).

Use with care! Same as self.to_subset but without any property checks. Always succeeds.
