Function Documentation

AFAPI af_err af_stdev	(	af_array *	out,
		const af_array	in,
		const dim_t	dim
	)

C Interface for standard deviation.

Parameters

[out]	out	will contain the standard deviation of the input array along dimension dim
[in]	in	is the input array
[in]	dim	the dimension along which the standard deviation is extracted

Returns

AF_SUCCESS if the operation is successful, otherwise an appropriate error code is returned.

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

C Interface for standard deviation of all elements.

Parameters

[out]	real	will contain the real part of standard deviation of the entire input array
[out]	imag	will contain the imaginary part of standard deviation of the entire input array
[in]	in	is the input array

Returns

AF_SUCCESS if the operation is successful, otherwise an appropriate error code is returned.

AFAPI array af::stdev	(	const array &	in,
		const dim_t	dim = -1
	)

C++ Interface for standard deviation.

Parameters

[in]	in	is the input array
[in]	dim	the dimension along which the standard deviation is extracted

Returns

the standard deviation of the input array along dimension dim

Note

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

AFAPI T af::stdev

(

const array &

in

)

C++ Interface for standard deviation of all elements.

Parameters

[in]

in

is the input array

Returns

standard deviation of the entire input array
