* Purpose\n\
* =======\n\
*\n\
* ICMAX1 finds the index of the element whose real part has maximum\n\
* absolute value.\n\
*\n\
* Based on ICAMAX from Level 1 BLAS.\n\
* The change is to use the 'genuine' absolute value.\n\
*\n\
* Contributed by Nick Higham for use with CLACON.\n\
*\n\n\
* Arguments\n\
* =========\n\
*\n\
* N (input) INTEGER\n\
* The number of elements in the vector CX.\n\
*\n\
* CX (input) COMPLEX array, dimension (N)\n\
* The vector whose elements will be summed.\n\
*\n\
* INCX (input) INTEGER\n\
* The spacing between successive values of CX. INCX >= 1.\n\
