NAME

icmax1 - find the index of the element whose real part has maximum absolute value

SYNOPSIS

INTEGER FUNCTION
ICMAX1( N, CX, INCX )

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

INTEGER INCX, N

COMPLEX CX( ∗ )

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.
