Detailed Description

Replace elements of an array with elements of another array.

Input values are retained when corresponding elements from the conditional array are true. Input values are replaced when corresponding elements from the conditional array are false.

Function Documentation

◆ af_replace()

AFAPI af_err af_replace	(	af_array	a,
		const af_array	cond,
		const af_array	b
	)

C Interface to replace elements of an array with elements of another array.

Elements of a are replaced with corresponding elements of b when cond is false.

Parameters

[in,out]	a	input array
[in]	cond	conditional array
[in]	b	replacement array

Returns: AF_SUCCESS, if function returns successfully, else an af_err code is given

◆ af_replace_scalar()

AFAPI af_err af_replace_scalar	(	af_array	a,
		const af_array	cond,
		const double	b
	)

C Interface to replace elements of an array with a scalar value.

Elements of a are replaced with a scalar value when cond is false.

Parameters

[in,out]	a	input array
[in]	cond	conditional array
[in]	b	replacement scalar value

Returns: AF_SUCCESS, if function returns successfully, else an af_err code is given

◆ af_replace_scalar_long()

AFAPI af_err af_replace_scalar_long	(	af_array	a,
		const af_array	cond,
		const long long	b
	)

C Interface to replace elements of an array with a scalar value.

Elements of a are replaced with a scalar value when cond is false.

Parameters

[in,out]	a	input array
[in]	cond	conditional array
[in]	b	replacement scalar value

Returns: AF_SUCCESS, if function returns successfully, else an af_err code is given

◆ af_replace_scalar_ulong()

AFAPI af_err af_replace_scalar_ulong	(	af_array	a,
		const af_array	cond,
		const unsigned long long	b
	)

C Interface to replace elements of an array with a scalar value.

Elements of a are replaced with a scalar value when cond is false.

Parameters

[in,out]	a	input array
[in]	cond	conditional array
[in]	b	replacement scalar value

Returns: AF_SUCCESS, if function returns successfully, else an af_err code is given

◆ replace() [1/4]

AFAPI void replace	(	array &	a,
		const array &	cond,
		const array &	b
	)

C++ Interface to replace elements of an array with elements of another array.

Elements of a are replaced with corresponding elements of b when cond is false.

Parameters

[in,out]	a	input array
[in]	cond	conditional array
[in]	b	replacement array

Examples: pde/bhrt.cpp, and pde/boltzmann_cfd.cpp.

◆ replace() [2/4]

AFAPI void replace	(	array &	a,
		const array &	cond,
		const double &	b
	)

C++ Interface to replace elements of an array with a scalar value.

Elements of a are replaced with a scalar value when cond is false.

Parameters

[in,out]	a	input array
[in]	cond	conditional array
[in]	b	replacement scalar value

◆ replace() [3/4]

AFAPI void replace	(	array &	a,
		const array &	cond,
		const long long	b
	)

C++ Interface to replace elements of an array with a scalar value.

Elements of a are replaced with a scalar value when cond is false.

Parameters

[in,out]	a	input array
[in]	cond	conditional array
[in]	b	replacement scalar value

◆ replace() [4/4]

AFAPI void replace	(	array &	a,
		const array &	cond,
		const unsigned long long	b
	)

C++ Interface to replace elements of an array with a scalar value.

Elements of a are replaced with a scalar value when cond is false.

Parameters

[in,out]	a	input array
[in]	cond	conditional array
[in]	b	replacement scalar value
