Struct BatchedTriSolve 

pub struct BatchedTriSolve { /* private fields */ }

Batched sparse triangular solve.

Solves L_i * x_i = b_i for each lower-triangular CSR matrix L_i and right-hand side b_i in the batch.

Implementations

impl BatchedTriSolve

pub fn new() -> Self

Create a new batched triangular solve executor.

pub fn execute<T: GpuFloat + Add<Output = T> + Mul<Output = T> + AddAssign>( l_batch: &[CsrMatrix<T>], b_batch: &[Vec<T>], ) -> SparseResult<Vec<Vec<T>>>

Execute batched forward-substitution on the host.

Each L_i must be square and lower-triangular with non-zero diagonal.

Errors

Returns SparseError::InvalidArgument on batch size mismatch. Returns SparseError::DimensionMismatch if matrices are not square. Returns SparseError::SingularMatrix if a zero diagonal is encountered. Returns SparseError::Cuda on download failure.

pub fn execute_host<T: GpuFloat + Add<Output = T> + Mul<Output = T> + AddAssign>( row_ptrs: &[Vec<i32>], col_indices: &[Vec<i32>], values: &[Vec<T>], sizes: &[usize], rhs: &[Vec<T>], ) -> SparseResult<Vec<Vec<T>>>

Execute batched forward-substitution from host-side arrays.

Errors

Returns SparseError::InvalidArgument on length mismatch. Returns SparseError::SingularMatrix on zero diagonal.
