:fortran_help: " DOUBLE PRECISION FUNCTION DZSUM1( N, CX, INCX )\n\n\
* Purpose\n\
* =======\n\
*\n\
* DZSUM1 takes the sum of the absolute values of a complex\n\
* vector and returns a double precision result.\n\
*\n\
* Based on DZASUM from the Level 1 BLAS.\n\
* The change is to use the 'genuine' absolute value.\n\
*\n\
* Contributed by Nick Higham for use with ZLACON.\n\
*\n\n\
* Arguments\n\
* =========\n\
*\n\
* N (input) INTEGER\n\
* The number of elements in the vector CX.\n\
*\n\
* CX (input) COMPLEX*16 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 > 0.\n\
