Calculates the sum of the absolute values of elements in a vector. For complex vectors, the VI calculates the sum of the absolute values of the real and imaginary parts of elements in a vector.

The data type you wire to the x input determines the polymorphic instance to use.

dasum - Absolute Values Sum (DBL)

	xInc determines whether the VI skips elements in x for the calculation. The default is 1, meaning the VI does not skip any elements in x. xInc is an optional input. xInc must be greater than zero. Note  If you wire a value other than the default to xInc, the VI skips elements that have indexes that are multiples of the value you wire. If you wire a value that is greater than or equal to the number of elements in x, the VI uses only the first element in x for the calculation.
	x is a real vector.
	dasum is a real scalar that returns the sum of the absolute values of elements in x.
	error returns any error or warning from the VI. You can wire error to the Error Cluster From Error Code VI to convert the error code or warning into an error cluster.

	xInc determines whether the VI skips elements in x for the calculation. The default is 1, meaning the VI does not skip any elements in x. xInc is an optional input. xInc must be greater than zero. Note  If you wire a value other than the default to xInc, the VI skips elements that have indexes that are multiples of the value you wire. If you wire a value that is greater than or equal to the number of elements in x, the VI uses only the first element in x for the calculation.
	x is a real vector.
	dzasum is a complex scalar that returns the sum of the absolute values of the real and imaginary parts of elements in x.
	error returns any error or warning from the VI. You can wire error to the Error Cluster From Error Code VI to convert the error code or warning into an error cluster.
