Function Documentation

af_imin()

AFAPI af_err af_imin	(	af_array *	out,
		af_array *	idx,
		const af_array	in,
		const int	dim
	)

C Interface for getting minimum values and their locations in an array.

Parameters

[out]	out	will contain the minimum of all values in in along dim
[out]	idx	will contain the location of minimum of all values in in along dim
[in]	in	is the input array
[in]	dim	The dimension along which the minimum value is extracted

Returns

AF_SUCCESS if the execution completes properly

af_imin_all()

AFAPI af_err af_imin_all	(	double *	real,
		double *	imag,
		unsigned *	idx,
		const af_array	in
	)

C Interface for getting minimum value and its location from the entire array.

Parameters

[out]	real	will contain the real part of minimum value of all elements in input in
[out]	imag	will contain the imaginary part of minimum value of all elements in input in
[out]	idx	will contain the location of minimum of all values in in
[in]	in	is the input array

Returns

AF_SUCCESS if the execution completes properly

Note

imag is always set to 0 when in is real.

af_min()

AFAPI af_err af_min	(	af_array *	out,
		const af_array	in,
		const int	dim
	)

C Interface for minimum values in an array.

Parameters

[out]	out	will contain the minimum of all values in in along dim
[in]	in	is the input array
[in]	dim	The dimension along which the minimum value is extracted

Returns

AF_SUCCESS if the execution completes properly

af_min_all()

AFAPI af_err af_min_all	(	double *	real,
		double *	imag,
		const af_array	in
	)

C Interface for getting minimum value of an array.

Parameters

[out]	real	will contain the real part of minimum value of all elements in input in
[out]	imag	will contain the imaginary part of minimum value of all elements in input in
[in]	in	is the input array

Returns

AF_SUCCESS if the execution completes properly

Note

imag is always set to 0 when in is real.

min() [1/4]

AFAPI void min	(	array &	val,
		array &	idx,
		const array &	in,
		const int	dim = -1
	)

C++ Interface for getting minimum values and their locations in an array.

Parameters

[out]	val	will contain the minimum values along dimension dim
[out]	idx	will contain the locations of minimum all values along dimension dim
[in]	in	is the input array
[in]	dim	The dimension along which the minimum value needs to be extracted

Note

dim is -1 by default. -1 denotes the first non-singleton dimension.

NaN values are ignored

C++ Interface for minimum values in an array.

Parameters

[in]	in	is the input array
[in]	dim	The dimension along which the minimum value needs to be extracted

Returns

result of minimum all values along dimension dim

Note

dim is -1 by default. -1 denotes the first non-singleton dimension.

NaN values are ignored

min() [4/4]

void min	(	T *	val,
		unsigned *	idx,
		const array &	in
	)

C++ Interface for getting minimum value and its location from the entire array.
