rand()
Catalog
>
rand() ⇒ expression
rand(#Trials) ⇒ list
rand() returns a random value between 0 and 1.
rand(#Trials) returns a list containing #Trials random values
between 0 and 1.
randBin()
Catalog
>
randBin(n, p) ⇒ expression
randBin(n, p, #Trials) ⇒ list
randBin(n, p) returns a random real number from a specified
Binomial distribution.
randBin(n, p, #Trials) returns a list containing #Trials random real
numbers from a specified Binomial distribution.
randInt()
Catalog
>
randInt(lowBound,upBound) ⇒ expression
randInt(lowBound,upBound ,#Trials) ⇒ list
randInt(lowBound,upBound) returns a random integer within the
range specified by lowBound and upBound integer bounds.
randInt(lowBound,upBound ,#Trials) returns a list containing
#Trials random integers within the specified range.
randMat()
Catalog
>
randMat(numRows, numColumns) ⇒ matrix
Returns a matrix of integers between -9 and 9 of the specified
dimension.
Both arguments must simplify to integers.
Note: The values in this matrix will change each time you press
·.
randNorm( )
Catalog
>
randNorm(m, s) ⇒ expression
randNorm(m, s, #Trials) ⇒ list
randNorm(m, s) returns a decimal number from the specified
normal distribution. It could be any real number but will be heavily
concentrated in the interval [mN3·s, m+3·s].
randNorm(m, s, #Trials) returns a list containing #Trials decimal
numbers from the specified normal distribution.
Sets the random-number seed.
