Count non-zero values in an array along a given dimension.
The output type is u32.
This function runs across all batches in the input simultaneously.
◆ af_count()
C Interface to count non-zero values in an array along a given dimension.
NaN values are treated as non-zero.
- Parameters
-
[out] out count [in] in input array [in] dim dimension along which the count occurs
- Returns
- AF_SUCCESS, if function returns successfully, else an af_err code is given
◆ af_count_all()
C Interface to count non-zero values over all dimensions.
- Parameters
-
[out] real count [out] imag 0 [in] in input array
- Returns
- AF_SUCCESS, if function returns successfully, else an af_err code is given
◆ af_count_all_array()
C Interface to count non-zero values over all dimensions.
- Parameters
-
[out] out count [in] in input array
- Returns
- AF_SUCCESS, if function returns successfully, else an af_err code is given
◆ count() [1/2]
| T count | ( | const array & | in | ) |
C++ Interface to count non-zero values along the first non-singleton dimension.
NaN values are treated as non-zero.
- Parameters
- Returns
- count
◆ count() [2/2]
C++ Interface to count non-zero values in an array along a given dimension.
NaN values are treated as non-zero.
- Parameters
-
[in] in input array [in] dim dimension along which the count occurs, -1 denotes the first non-singleton dimension
- Returns
- count
