icamax(3P)
NAME
icamax - Return the index of the element with largest absolute value.
SYNOPSIS
INTEGER FUNCTION ICAMAX (N, X, INCX)
INTEGER INCX, N
COMPLEX X( ∗ )
#include <sunperf.h>
int icamax(int n, complex ∗cx, int incx) ;
PURPOSE
ICAMAX - 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 subroutine to have any visible effect. Unchanged on exit.
X - COMPLEX 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.
