IZMAX1 (3lapack)


SYNOPSIS

  INTEGER FUNCTION IZMAX1( N, CX, INCX )

      INTEGER      INCX, N

      COMPLEX*16   CX( * )

PURPOSE

  IZMAX1 finds the index of the element whose real part has maximum absolute
  value.

  Based on IZAMAX from Level 1 BLAS.
  The change is to use the 'genuine' absolute value.
