INFLMAX (3sciport)

Searches for the maximum vector element subfield

SYNOPSIS

  index = INFLMAX( n, x, incx, mask, shift )

FUNCTION VALUE

  inflmax         Integer.
                  The index in x of the first occurrence of maximum subfield
                  value.

ARGUMENTS

  n               Integer.
                  The number of elements of x to be searched.

  x               Integer vector.
                  The input vector.

  incx            Integer.
                  The increment between elements of vector x.

  mask            Integer.
                  A right justified bit mask used to extract the subfield
                  from x.

  shift           Integer.
                  The number of bits to right shift each element before
                  extracting the subfield.

DESCRIPTION

  Integer function INFLMAX searches input vector x for the maximum value of a
  selected subfield of each element. The index of the first occurrence of the
  maximum found in x is returned.
