Calling Sequence
g05mac(a, b, n, x, igen, iseed, 'fail'=fail)
nag_rngs_discrete_uniform(. . .)
Parameters
|
|
a - integer;
b - integer;
|
|
|
|
On entry: the end points  and  of the uniform distribution.
|
|
|
Constraint:  . .
|
|
|
|
n - integer;
|
|
|
|
On entry:  , the number of pseudo-random numbers to be generated.
|
|
|
Constraint:  . .
|
|
|
|
x - Vector(1..dim, datatype=integer[kernelopts('wordsize')/8]);
|
|
|
|
Note: the dimension, dim, of the array x must be at least  .
|
|
|
On exit: the  pseudo-random numbers from the specified uniform distribution.
|
|
|
|
iseed - Vector(1.. , datatype=integer[kernelopts('wordsize')/8]);
|
|
|
|
On entry: contains values which define the current state of the selected generator.
|
|
|
On exit: contains updated values defining the new state of the selected generator.
|
|
|
|
'fail'=fail - table; (optional)

Purpose
|
|
nag_rngs_discrete_uniform (g05mac) generates a vector of pseudo-random integers uniformly distributed over the interval ![[a,,,b]](/support/helpjp/helpview.aspx?si=9885/file08509/math111.png) .
