NI-DSP Analysis VI Reference 
Chapter 2
Part 3:  NI-DSP Function Reference 2-5 NI-DSP SRM for LabVIEW for Windows
DSP Add
Add array X to array Y.  The i
th
 element of the
output array Z is obtained using the following
formula:
Z(i) = X(i) + Y(i).
for  i = 0, 1, 2, … , n-1
where n is the smaller number of elements in and Y.
X is a DSP Handle Cluster that indicates the memory buffer on the DSP board that contains the input
signal array X.
Y is a DSP Handle Cluster that indicates the memory buffer on the DSP board that contains the input
signal array Y.
Z in is a DSP Handle Cluster that indicates the memory buffer on the DSP board that will contain the
results of X(i) + Y(i).
Z out is a DSP Handle Cluster that is identical to Z in, but with the added results already stored in the
memory buffer on the DSP board.
error in (no error) contains the error information from a previous VI.  If an error occurs, it is passed out
error out and no other calls are made.
error out contains the error information for this call.
The operation can be performed in place; that is, the input and output arrays can be the same DSP Handle Cluster.
