SYNOPSIS
Functions/Subroutines
double precision function dzsum1 (n, cx, incx)
DZSUM1 forms the 1-norm of the complex vector using the true absolute
value.
Function/Subroutine Documentation
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.
INCX
INCX is INTEGER The spacing between successive values of CX. INCX > 0.
