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

Function Documentation

AFAPI af_err af_sum ( af_array out,
const af_array  in,
const int  dim 
)

C Interface for sum of elements in an array.

Parameters
[out]outwill contain the sum of all values in in along dim
[in]inis the input array
[in]dimThe dimension along which the add operation occurs
Returns
AF_SUCCESS if the execution completes properly
AFAPI af_err af_sum_all ( double *  real,
double *  imag,
const af_array  in 
)

C Interface for sum of all elements in an array.

Parameters
[out]realwill contain the real part of adding all elements in input in
[out]imagwill contain the imaginary part of adding 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::sum ( const array in,
const int  dim = -1 
)

C++ Interface for sum of elements in an array.

Parameters
[in]inis the input array
[in]dimThe dimension along which the add operation occurs
Returns
result of sum all values along dimension dim
Note
dim is -1 by default. -1 denotes the first non-singleton dimension.
Examples:
deep_belief_net.cpp, integer.cpp, kmeans.cpp, logistic_regression.cpp, naive_bayes.cpp, rainfall.cpp, rbm.cpp, and vectorize.cpp.
T af::sum ( const array in)

C++ Interface for sum of all elements in an array.

Parameters
