Random Uniform Source

Uniform Random Number Generator

Generates a number of samples of random numbers of [min, max) meaning the max value won't be included. Repeat samples if specified. Great for creating bytes of information for a modulator.

Ex: With min=0 and max=2, the sequence 01110101... will be generated.

Supports an output of type int, short, and byte.

This block differs from Random Source in the pseudorandom number generator used. This block implements the xoroshiro128+ algorithm in C++ which has been shown to be require much less processing time than the MT19937 algorithm used by Numpy in Random Source. The disadvantage of the xoroshiro128+ algorithm is it fails the Hamming-weight dependencies test after 5TB of generated values and thus is unsuitable for generating many random values if "optimal pseudo-randomness" is required.

TL;DR: This block operates faster than Random Source but uses a less "pseudorandom" algorithm.

Parameters

minimum

defines minimal integer value output.

maximum

output values are below this value

seed

for Pseudo Random Number Generator. Defaults to 0. In this case current time is used.
