mode

Functions

int main(int argc, char *argv[])

mode [ option ] [ infile ]

  • -l int

    • length of vector \((1 \le M + 1)\)

  • -m int

    • order of vector \((0 \le M)\)

  • -b int

    • find \(N\)-best values \((1 \le N)\)

  • -w int

    • way to find value

      • 0 find value from a vector

      • 1 find value from vector sequence for each dimension

  • -c str

    • int-type counts

  • infile str

    • double-type data sequence

  • stdout

    • double-type mode
