Does Labview have a Random Number Generator for U16 with a periodicity greater than 64 Million instances of U16words and one with SEED as the connector?
We are doing some testing that requires 64MegaWords be written to our DSP memory with random values to do a validity check and without repeating sequences with using the previous value as the seed for the next and us passing it the initial seed. The dice one doesn't meet that criteria, and I was not sure how the continuous random number generator parameters work and if any of them would meet this criteria. Anyone have any information that might help?
This is the only built-in LabVIEW function that generates a random number. You can create your own function or you can use a function in a another programming language, put it in a dll, that uses the C or stdcall (WINAPI) calling conventions. Then you can call that dll from LabVIEW.
There is no reason why you couldn't simply write a pseudo-random number generator by yourself. Simply select a random number algorithm you want to use and implement it in LabVIEW. You do not need to interface code written in another language in order to implement a pseudorandom number generator. If you have a DAQ card or something, you can also use inputr noise or some other hardware soruce to generate real random numbers. For that also LabVIEW is an excellent tool.
You could also try the "Uniform White Noise" function with the "samples" input set to 1. The online help for that function indicates "The pseudorandom sequence produces approximately 290 samples before
the pattern repeats itself".
Note: The "Uniform White Noise" function is not in the "Base" package.
