Paramètres

  • sampleValue
    Type : System. . :: . .Int32
    An Int32 value that specifies the sample size. The units are dependent on the scan type.
  • recompute
    Type : System. . :: . .Boolean
    A Boolean value that specifies whether to recompute the statistics.
    If True, the statistics are recomputed.
    If False, the statistics are not recomputed.
