Class sparse_norm

java.lang.Object

apple.accelerate.enums.sparse_norm

public final class sparse_norm
extends java.lang.Object

The norm specifier [@constant] SPARSE_NORM_ONE Matrix element wise: sum over i,j ( | A[i,j] | )

Matrix operator : max over j ( sum over i ( | A[i,j] | )

Vector element wise: sum over i ( | x[i] | )

[@constant] SPARSE_NORM_TWO Matrix element wise: sqrt( sum over i,j (A[i,j])^2 )

Matrix operator : Largest singular value of matrix, note that the operator SPARSE_NORM_TWO is significantly more expensive than other norm operations.

Vector element wise: sqrt( sum over i (x[i])^2 )

[@constant] SPARSE_NORM_INF Matrix element wise: max over i,j ( | A[i,j] | )

Matrix operator : max over i ( sum over j ( | A[i,j] | )

Vector element wise: max over i ( | x[i] | )

[@constant] SPARSE_NORM_R1 Matrix element wise: sum over j ( sqrt ( sum over i ( A[i,j]^2 ) ) )

Matrix operator : Not supported. Undefined

Vector element wise: Not supported. Undefined
