Find the covariance of values in the input
This function performs the operation across all dimensions of the input array.
◆ af_cov()
C Interface for covariance.
- Parameters
-
[out] | out | will the covariance of the input arrays |
[in] | X | is the first input array |
[in] | Y | is the second input array |
[in] | isbiased | is boolean specifying if biased estimate should be taken (default: false) |
- Returns
- AF_SUCCESS if the operation is successful, otherwise an appropriate error code is returned.
- Deprecated
- Use af_cov_v2 instead
◆ af_cov_v2()
C Interface for covariance.
- Parameters
-
[out] | out | will the covariance of the input arrays |
[in] | X | is the first input array |
[in] | Y | is the second input array |
[in] | bias | The type of bias used for variance calculation. Takes of value of type af_var_bias |
- Returns
- AF_SUCCESS if the operation is successful, otherwise an appropriate error code is returned.
◆ cov() [1/2]
C++ Interface for covariance.
- Parameters
-
[in] | X | is the first input array |
[in] | Y | is the second input array |
[in] | bias | The type of bias used for variance calculation. Takes of value of type af_var_bias. |
- Returns
- the covariance of the input arrays
◆ cov() [2/2]
C++ Interface for covariance.
- Parameters
-
[in] | X | is the first input array |
[in] | Y | is the second input array |
[in] | isbiased | is boolean specifying if biased estimate should be taken (default: false) |
- Returns
- the covariance of the input arrays
- Deprecated
- Use af::cov(const array&, const array& const af_var_bias)
