# ReductionType

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

### Synopsis

    /* NOTE: The integer 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. */typedef enum {REDUCTION_SUM_REALPART=10,
                  REDUCTION_MEAN_REALPART=11,
                  REDUCTION_SUM_IMAGINARYPART=12,
                  REDUCTION_MEAN_IMAGINARYPART=13
                  } ReductionType;
