Specifying two integer values for the argument generates random numbers between them.

Problem

Operation

mth

abc

cat

2D

Generate random numbers
between 0 and 1.

Func

S “randList” Function

Syntax: randList(n [, a, b])

Function:
• Omitting arguments “a” and “b” returns a list of

n

elements that contain decimal random

values.

• Specifying arguments “a” and “b” returns a list of

n

elements that contain integer random

values in the range of “a” through “b”.

Description:
• “

n

” must be a positive integer.

• The random numbers of each element are generated in accordance with “RandSeed”

specifications, as with the “rand” function.

mean σ and standard deviation μ values.

Syntax: randNorm(σ, μ [, n])

Function:
• Omitting a value for “n” (or specifying 1 for “n”) returns the generated random number as-is.
• Specifying a value for “n” returns the specified number of random values in list format.
