Class core.LFSR_NR

Synopsis: Non-repeating Pseudo random number generator (linear feedback shift register).

  Methods: Description:


Warning: This is meant for _small_ random arrays (e.g. a sequence of 32 random values). It becomes exponentially slower with larger array sizes, e.g.: len= 8: ~9.1 mrand/sec len= 16: ~7.0 mrand/sec len= 32: ~5.8 mrand/sec len= 64: ~4.2 mrand/sec len= 128: ~2.9 mrand/sec len= 256: ~1.9 mrand/sec len= 512: ~1.1 mrand/sec len=1024: ~0.6 mrand/sec len=2048: ~0.3 mrand/sec len=4096: ~0.15 mrand/sec (see tks-examples/lfsr.tks)
