NAME
izamax - Return the index of the element with largest abso-
lute value.
SYNOPSIS
INTEGER FUNCTION IZAMAX (N, X, INCX)
INTEGER INCX, N
COMPLEX*16 X( * )
#include <sunperf.h>
int izamax(int n, doublecomplex *zx, int incx) ;
PURPOSE
IZAMAX - Return the index of the element in x with largest
absolute value where x is an n-vector and absolute value is
defined as the sum of the absolute value of the real part
and the absolute value of the imaginary part.
PARAMETERS
N - INTEGER.
On entry, N specifies the number of elements in
the vector. N must be at least one for the sub-
routine to have any visible effect. Unchanged on
exit.
X - COMPLEX*16 array of DIMENSION at least
( 1 + ( m - 1 )*abs( INCX ) ). On entry, the
incremented array X must contain the vector x.
Unchanged on exit.
INCX - INTEGER.
On entry, INCX specifies the increment for the
elements of X. INCX must be positive. Unchanged
on exit.
