Function/Subroutine Documentation

INTEGER function icmax1 (integerN, complex, dimension( * )CX, integerINCX)

ICMAX1 finds the index of the vector element whose real part has maximum absolute value.

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.

Parameters:

N 



          N is INTEGER


          The number of elements in the vector CX.

CX



          CX is COMPLEX array, dimension (N)


          The vector whose elements will be summed.

INCX



          INCX is INTEGER


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