Generates a Gaussian distributed
pseudorandom pattern whose
statistical profile is as follows:

(

µ

, 

σ

)  =  (0, s) ,

where s is the absolute value of the
specified standard deviation.

standard deviation defaults to 1.0.

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

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

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

Gaussian Pattern out is a DSP Handle Cluster that is identical to Gaussian  Pattern in, but with the
generated pattern already stored in the memory buffer on the DSP board.  The largest Gaussian 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.
