National Instruments 320571-01 用户手册

Generates a uniformly distributed
pseudorandom pattern whose values
are in the range [0:1].  The sequence is
generated using the Very-Long-Cycle
random number generator algorithm.

seed < 65536.0.  If seed > 0.0, the generated noise will be the same in repeated invocations if the seed
value does not change.  If seed 

≤

 0.0, the VI generates a random value to use as the seed, and the noise

differs in repeated invocations although the value in seed does not change.  seed defaults to 0.0.

Random Pattern in is a DSP Handle Cluster that indicates the memory buffer on the DSP board that
will contain the output random pattern.

Random Pattern out is a DSP Handle Cluster that is identical to Random Pattern in, but with the
generated pattern already stored in the memory buffer on the DSP board.  The largest random pattern
that can be generated depends upon the amount of memory on your 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.
