NAME    [Toc]    [Back]

     idamax, isamax, izamax, icamax - BLAS Maximum index functions

FORTRAN	77 SYNOPSIS
     integer function idamax( n, x, incx )
     integer	       incx, n
     double precision  x( 1 )

     integer function isamax( n, x, incx )
     integer	      incx, n
     real	      x( 1 )

     integer function izamax( n, x, incx )
     integer	      incx, n
     complex*16	      x( 1 )

     integer function icamax( n, x, incx )
     integer	      incx, n
     complex	      x( 1 )

C SYNOPSIS    [Toc]    [Back]

     Integer idamax( n,	x, incx	)
     Integer	       incx, n;
     double	       (*x)[ n ];

     Integer isamax( n,	x, incx	)
     Integer	      incx, n;
     float	      (*x)[ n ];

     Integer izamax( n,	x, incx	)
     Integer	      incx, n;
     Zomplex	      (*x)[ n ];

     Integer icamax( n,	x, incx	)
     Integer	      incx, n;
     Complex	      (*x)[ n ];

DESCRIPTION    [Toc]    [Back]

     idamax, isamax, izamax, and icamax, return	the index of the maximum value
     of	vector x.  The vector x	has length n and increment incx.
     For izamax	and icamax , the norm of each value is taken as:

	   Abs(	Real( x(i) ) ) + Abs( Imag( x(i) ) )
