IILZ (3sciport)

Returns the number of leading zero elements in a vector

SYNOPSIS

  kount = IILZ( n, x, incx )

FUNCTION VALUE

  iilz            Integer.
                  Number of zero values in a vector before the first nonzero
                  value. The vector can be of type integer, logical, or real.

ARGUMENTS

  n               Integer.
                  The number of elements in the vector.

  x               Integer, Logical, or Real vector.
                  An input vector of length x.

  incx            Integer.
                  The increment between elements of vector x. For contiguous
                  elements, incx = 1.

DESCRIPTION

  The function IILZ returns the number of zero values before the first
  nonzero value in an array. It returns zero if the number of elements, n, is
  less than one.
