Struct heron::rapier_plugin::rapier::utils::SdpMatrix2 [−]
A 2x2 symmetric-definite-positive matrix.
Fields
m11: N
The component at the first row and first column of this matrix.
m12: N
The component at the first row and second column of this matrix.
m22: N
The component at the second row and second column of this matrix.
Implementations
impl<N> SdpMatrix2<N> where
N: SimdRealField,
N: SimdRealField,
pub fn new(m11: N, m12: N, m22: N) -> SdpMatrix2<N>
A new SDP 2x2 matrix with the given components.
Because the matrix is symmetric, only the lower off-diagonal component is required.
pub fn from_sdp_matrix(
mat: Matrix<N, U2, U2, <DefaultAllocator as Allocator<N, U2, U2>>::Buffer>
) -> SdpMatrix2<N>
mat: Matrix<N, U2, U2, <DefaultAllocator as Allocator<N, U2, U2>>::Buffer>
) -> SdpMatrix2<N>
Build an SdpMatrix2
structure from a plain matrix, assuming it is SDP.
No check is performed to ensure mat
is actually SDP.
pub fn zero() -> SdpMatrix2<N>
Create a new SDP matrix filled with zeros.
pub fn diagonal(val: N) -> SdpMatrix2<N>
Create a new SDP matrix with its diagonal filled with val
, and its off-diagonal elements set to zero.
pub fn add_diagonal(&mut self, elt: N) -> SdpMatrix2<N>
Adds val
to the diagonal components of self
.
pub fn inverse_unchecked(&self) -> SdpMatrix2<N>
Compute the inverse of this SDP matrix without performing any inversibility check.
pub fn into_matrix(
self
) -> Matrix<N, U2, U2, <DefaultAllocator as Allocator<N, U2, U2>>::Buffer>
self
) -> Matrix<N, U2, U2, <DefaultAllocator as Allocator<N, U2, U2>>::Buffer>
Convert this SDP matrix to a regular matrix representation.
