SYNOPSIS

INTEGER FUNCTION ICMAX1( N, CX, INCX )

INTEGER INCX, N

COMPLEX CX( ∗ )

#include <sunperf.h>

int icmax1(int n, complex ∗cx, int ∗incx) ;

PURPOSE

ICMAX1 finds the index of the element whose real part has maximum absolute value. 
 
Based on ICAMAX from Level 1 BLAS.
The change is to use the ’genuine’ absolute value.
 
Contributed by Nick Higham for use with CLACON.
