Function triangular_solve_backend 

pub fn triangular_solve_backend<T>(
    a: &TypedTensor<T>,
    b: &TypedTensor<T>,
    left_side: bool,
    lower: bool,
    transpose_a: bool,
    unit_diagonal: bool,
) -> Result<TypedTensor<T>, BackendLinalgError>
where
    T: BackendLinalgScalar,

Solve a triangular system with the configured tenferro backend. If left_side is true, this solves op(A) X = B; otherwise it solves X op(A) = B. lower selects the triangular half, transpose_a applies a transpose to A, and unit_diagonal treats the diagonal of A as ones.

Errors

Returns an error when the solve fails (a backend, singular, or shape /// mismatch failure).
