Struct NativeRandomState

Namespace

NumSharp

Assembly

NumSharp.dll

Represents the stored state of MT19937 random number generator. This format is compatible with NumPy's random state.

public struct NativeRandomState

Inherited Members

ValueType.Equals(object)

ValueType.GetHashCode()

ValueType.ToString()

object.Equals(object, object)

object.GetType()

object.ReferenceEquals(object, object)

Extension Methods

LinqExtensions.Yield<T>(T)

Remarks

NumPy state format: ('MT19937', array([...624...]), pos, has_gauss, cached_gaussian)

Constructors

NativeRandomState(byte[])

Backward compatibility constructor for legacy byte[] state. This will throw if called with old-format state.

[Obsolete("Legacy Randomizer state format is no longer supported. Use new MT19937-based state.")]
public NativeRandomState(byte[] state)

Parameters

state byte[]

NativeRandomState(uint[], int, int, double)

Creates a new NativeRandomState with default values.

public NativeRandomState(uint[] key, int pos, int hasGauss = 0, double cachedGaussian = 0)

Parameters

key uint[]

pos int

hasGauss int

cachedGaussian double

Fields

Algorithm

Algorithm identifier. Always "MT19937" for NumPy-compatible state.

public string Algorithm

Field Value

string

CachedGaussian

The cached Gaussian value from Box-Muller transform.

public double CachedGaussian

Field Value

double

HasGauss

Whether there is a cached Gaussian value (0 or 1).

public int HasGauss

Field Value

int

Key

The MT19937 state array (624 uint32 values).

public uint[] Key

Field Value

uint[]

Pos

Current position in the state array (0-624).

public int Pos

Field Value

int
