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)
