Detailed Description

Function Documentation

template<typename ForwardIterator , typename T >

void bolt::amp::fill	(	const bolt::amp::control &	ctl,
		ForwardIterator	first,
		ForwardIterator	last,
		const T &	value
	)

Fill assigns the value of value to each element in the range [first,last].

Parameters

ctl	Optional Control structure to control accelerator, debug, tuning, etc.See bolt::amp::control.
first	The first element in the range of interest.
last	The last element in the range of interest.
value	Sets this value to elements in the range [first,last].

Template Parameters

ForwardIterator	is a model of Forward Iterator, and InputIterator is mutable.
T	is a model of Assignable.

The following code snippet demonstrates how to fill a device_vector with a float value.

#include <bolt/amp/fill.h>
#include <bolt/amp/device_vector.h>
#include <stdlib.h>
...

bolt::amp::device_vector<float> v(10);

float x=25.0f;
bolt::amp::fill(v.begin(), v.end(), x);

// the elements of v are now assigned to the float value.

template<typename OutputIterator , typename Size , typename T >

OutputIterator bolt::amp::fill_n	(	const bolt::amp::control &	ctl,
		OutputIterator	first,
		Size	n,
		const T &	value
	)

fill_n assigns the value value to every element in the range [first,first+n]. The return value is first + n.

Parameters

ctl	Optional Control structure to control accelerator, debug, tuning, etc.See bolt::amp::control.
first	The first element in the range of interest.
n	The size of the range of interest.
value	Sets this value to elements in the range [first,first+n].

Template Parameters

OutputIterator	is a model of Output Iterator
Size	is an integral type (either signed or unsigned).
T	is a model of Assignable

Returns

first+n.

The following code snippet demonstrates how to fill a device_vector with a float value.

#include <bolt/amp/fill.h>
#include <bolt/amp/device_vector.h>
#include <stdlib.h>

...

bolt::amp::device_vector<float> v(10);

float x=25.0f;
bolt::amp::fill_n(v.begin(), 10, x);

// the elements of v are now assigned to the float value.
