This function performs the operation across all batches present in the input simultaneously.

Function Documentation

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]outwill contain the minimum of all values in in along dim
[out]idxwill contain the location of minimum of all values in in along dim
[in]inis the input array
[in]dimThe dimension along which the minimum value is extracted
Returns
AF_SUCCESS if the execution completes properly
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]realwill contain the real part of minimum value of all elements in input in
[out]imagwill contain the imaginary part of minimum value of all elements in input in
[out]idxwill contain the location of minimum of all values in in
[in]inis the input array
Returns
AF_SUCCESS if the execution completes properly
Note
imag is always set to 0 when in is real.
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]outwill contain the minimum of all values in in along dim
[in]inis the input array
[in]dimThe dimension along which the minimum value is extracted
Returns
AF_SUCCESS if the execution completes properly
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]realwill contain the real part of minimum value of all elements in input in
[out]imagwill contain the imaginary part of minimum value of all elements in input in
[in]inis the input array
Returns
AF_SUCCESS if the execution completes properly
Note
imag is always set to 0 when in is real.
AFAPI array af::min ( const array in,
const int  dim = -1 
)

C++ Interface for minimum values in an array.

Parameters
[in]inis the input array
[in]dimThe 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
