Function/Subroutine Documentation

INTEGER function izmax1 (integerN, complex*16, dimension( * )CX, integerINCX)

IZMAX1 finds the index of the vector element whose real part has maximum absolute value.

Purpose:

IZMAX1 finds the index of the element whose real part has maximum
absolute value.

Based on IZAMAX from Level 1 BLAS.
The change is to use the 'genuine' absolute value.

Parameters:

N

N is INTEGER
The number of elements in the vector CX.

CX

CX is COMPLEX*16 array, dimension (N)
The vector whose elements will be summed.

INCX

INCX is INTEGER
The spacing between successive values of CX.  INCX >= 1.
