L1Norm

num_valid::algorithms::vector_norms

Struct L1Norm 

Source 
pub struct L1Norm<Acc>(/* private fields */);
Expand description

Identifies the Manhattan (L1) norm, ‖v‖₁ = Σᵢ |vᵢ|.

The type parameter Acc selects the summation strategy for absolute values. Typical choices:

  • NaiveSum<R> — plain +=, fastest option.
  • NeumaierSum<R> — compensated summation, more accurate when components span many orders of magnitude.

L1Norm<Acc> implements VectorNorm and ParallelVectorNorm for any FpScalar whose RealType matches Acc::Input.
