Batch sampling from a Distribution

Name

UxHwDoubleSampleBatch, UxHwFloatSampleBatch — Store a batch of samples from a distribution to a destination array.

Synopsis

#include <stddef.h>
#include <uxhw.h>

void	UxHwDoubleSampleBatch(double value, double *  destSampleArray, size_t numberOfRandomSamples);
void	UxHwFloatSampleBatch(float value, float *  destSampleArray, size_t numberOfRandomSamples);

Description

The UxHwDoubleSampleBatch() function, on architectures that associate distributional information with floating-point values, draws numberOfRandomSamples random samples from the distribution associated with value and stores them in the destination array destSampleArray.

Parameters

• value — The distributional value to draw samples from.
• destSampleArray — The destination array where the samples will be stored.
• numberOfRandomSamples — The number of samples to be drawn and stored.

Return Values

The UxHwDoubleSampleBatch() function does not return a value.

✏️   Examples

#include <stddef.h>
#include <stdio.h>
#include <uxhw.h>

enum
{
	N = 10,
};

int
main(void)
{
	size_t  i;
	double  a;
	double  samples[N] = {0};

	a = UxHwDoubleUniformDist(10.0, 20.0);

	UxHwDoubleSampleBatch(a, samples, N);

	for (i = 0; i < 10; i++)
	{
		printf("Sample %d of %lf is %lf.\n", i, a, samples[i]);
	}

	return 0;
