g05tb generates a vector of pseudorandom logical values – true with probability p and false with probability 1-p.

Syntax

C#
public static void g05tb(
	int n,
	double p,
	G05..::..G05State g05state,
	bool[] x,
	out int ifail
)
Visual Basic
Public Shared Sub g05tb ( _
	n As Integer, _
	p As Double, _
	g05state As G05..::..G05State, _
	x As Boolean(), _
	<OutAttribute> ByRef ifail As Integer _
)
Visual C++
public:
static void g05tb(
	int n, 
	double p, 
	G05..::..G05State^ g05state, 
	array<bool>^ x, 
	[OutAttribute] int% ifail
)
F#
static member g05tb : 
        n : int * 
        p : float * 
        g05state : G05..::..G05State * 
        x : bool[] * 
        ifail : int byref -> unit

Parameters

n
Type: System..::..Int32
On entry: n, the number of pseudorandom logical values to be generated.
Constraint: n≥0.
p
Type: System..::..Double
On entry: must contain the probability of g05tb returning true.
Constraint: 0.0≤p≤1.0.
g05state
Type: NagLibrary..::..G05..::..G05State
An Object of type G05.G05State.
x
Type: array<System..::..Boolean>[]()[][]
An array of size [n]
On exit: the n logical values.
ifail
Type: System..::..Int32%
On exit: ifail=0 unless the method detects an error or a warning has been flagged (see [Error Indicators and Warnings]).

Description

g05tb generates n logical values xi from the relation
yi<p
where yi is a pseudorandom number from a uniform distribution over 0,1, generated by g05sa using the values of state as input to this method.
One of the initialization methods (G05KFF not in this release) (for a repeatable sequence if computed sequentially) or (G05KGF not in this release) (for a non-repeatable sequence) must be called prior to the first call to g05tb.
