kRandom Number Generator (rand, randList, RandSeed)
•The ClassPad random number generator can generate truly random numbers (non- sequential random numbers) and random numbers that follow a particular pattern (sequen- tial random numbers). Using the “randList” function, you can generate a list whose elements contain random numbers. There are nine different patterns for generation of sequential random numbers. Use the “RandSeed” command to switch between non- sequential and sequential random number generation, and to select the sequential random number generation pattern.
u ClassPad Operation
(1)Use the “RandSeed” command to configure random number generation settings, if required.
(2)Use the “rand” function or “randList” function to generate the random numbers.
