DZASUM
DZASUM takes the sum of the (|Re(.)| + |Im(.)|)'s of a complex vector and returns a double precision result.
[in] | N | N is INTEGER number of elements in input vector(s) |
[in,out] | ZX | ZX is COMPLEX*16 array, dimension ( 1 + ( N - 1 )*abs( INCX ) ) |
[in] | INCX | INCX is INTEGER storage spacing between elements of ZX |
