Struct CpuBatchedBlockSolver 

pub struct CpuBatchedBlockSolver;

Current CPU implementation of the BA batched block interface.

It is intentionally plain Rust loops because d is tiny. The trait shape, not this implementation, is the load-bearing part for the future MegBA or Ceres backend.

Trait Implementations

impl BatchedBlockSolver for CpuBatchedBlockSolver

fn factor_blocks( &self, rows: &[ArrowRowBlock], ridge_t: f64, d: usize, tolerate_ill_conditioning: bool, ) -> Result<ArrowFactorSlab, ArrowSchurError>

Factor every per-row point block H_tt^(i) + ridge_t I, as in BA’s point elimination stage.

fn solve_block_vector( &self, factor: ArrayView2<'_, f64>, rhs: ArrayView1<'_, f64>, ) -> Array1<f64>

Solve one factored point block against a vector RHS.

fn solve_block_matrix( &self, factor: ArrayView2<'_, f64>, rhs: ArrayView2<'_, f64>, ) -> Array2<f64>

Solve one factored point block against a dense matrix RHS.

fn sqrt_solve_block_matrix( &self, factor: ArrayView2<'_, f64>, rhs: ArrayView2<'_, f64>, ) -> Array2<f64>

Apply the Square-Root BA lower-triangular solve L_i^-1 rhs.

fn block_gemm_subtract( &self, schur: &mut Array2<f64>, left: &Array2<f64>, right: &Array2<f64>, )

Subtract a row-local Schur product from the dense reduced system.
