Chapter 2 NI-DSP Analysis VI Reference
NI-DSP SRM for LabVIEW for Windows 2-68 Part 3:  NI-DSP Function Reference
DSP Reverse
Reverse the order of the elements of the input
array X.
X is a DSP Handle Cluster that indicates the memory buffer on the DSP board that contains the input
signal array X.
The operation can only be performed in place; that is, the input X is overwritten by the output Reverse {X}.
Reverse {X} is a DSP Handle Cluster that is identical to the X, but with the reverse {X} 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.
