VectorSample Method (Int32, Decimal)

Returns a vector of the specified sampleSize containing non-repeating indices in the range [0, populationSize) in random order.

Namespace: Accord.Math
Assembly: Accord.Math (in Accord.Math.dll) Version: 3.8.0

Syntax

Copy

public static decimal[] Sample(
	int sampleSize,
	decimal populationSize
)

Public Shared Function Sample ( 
	sampleSize As Integer,
	populationSize As Decimal
) As Decimal()

Request Example View Source

Parameters

sampleSize: Type: SystemInt32
The size of the sample vector to be generated.
populationSize: Type: SystemDecimal
The non-inclusive maximum number an index can have.

Return Value

Type: Decimal

Remarks

In other words, this return a sample of size k from a population of size N, where k is the parameter sampleSize and N is the parameter populationSize.

Examples

Copy

var a = Vector.Sample(3, 10);  // a possible output is { 1, 7, 4 };
var b = Vector.Sample(10, 10); // a possible output is { 5, 4, 2, 0, 1, 3, 7, 9, 8, 6 };

foreach (var i in Vector.Sample(5, 6))
{
   // ...
}
