NAME

IZAMAX - Return the index of the element with largest absolute value. 

SYNOPSIS

INTEGER FUNCTION IZAMAX (N, X, INCX)

INTEGER INCX, N

COMPLEX∗16    X( ∗ )

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 subroutine 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.
