ReductionType

determines what type of column reduction (one that is not a type of norm defined in NormType) to compute

Synopsis

typedef enum {
  REDUCTION_SUM_REALPART       = 10,
  REDUCTION_MEAN_REALPART      = 11,
  REDUCTION_SUM_IMAGINARYPART  = 12,
  REDUCTION_MEAN_IMAGINARYPART = 13
} ReductionType;

Values

• REDUCTION_SUM_REALPART - sum of real part of each matrix column

• REDUCTION_SUM_IMAGINARYPART - sum of imaginary part of each matrix column

• REDUCTION_MEAN_REALPART - arithmetic mean of real part of each matrix column

• REDUCTION_MEAN_IMAGINARYPART - arithmetic mean of imaginary part of each matrix column

Developer Note

The constants defined in ReductionType MUST BE DISTINCT from those defined in NormType. This is because MatGetColumnReductions() is used to compute both norms and other types of reductions, and the constants defined in both NormType and ReductionType are used to designate the desired operation.
