double precision function dzsum1 (integer N, complex*16, dimension( * ) CX, integer INCX)DZSUM1 forms the 1-norm of the complex vector using the true absolute value​. Purpose: 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.Parameters: N N is INTEGER The number of elements in the vector CX.
CX CX is COMPLEX*16 array, dimension (N) The vector whose elements will be summed.
