DZSUM1
Download DZSUM1 + dependencies [TGZ] [ZIP] [TXT]DZSUM1 takes the sum of the absolute values of a complex vector and returns a double precision result. Based on DZASUM from the Level 1 BLAS. The change is to use the 'genuine' absolute value.
[in] | N | N is INTEGER The number of elements in the vector CX. |
[in] | CX | CX is COMPLEX*16 array, dimension (N) The vector whose elements will be summed. |
[in] | INCX | INCX is INTEGER The spacing between successive values of CX. INCX > 0. |
