Multiply array X  by 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 X
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 multiplied 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.
