DML_ELEMENT_WISE_ATAN_YX_OPERATOR_DESC structure (directml.h)

  • Article

Computes the 2-argument arctangent for each element of ATensor and BTensor, where ATensor is the Y-axis and BTensor is the X-axis, placing the result into the corresponding element of OutputTensor. This operator is undefined for the origin (that is, when ATensor and BTensor are both 0 for corresponding elements).

GRU_Forward

f(y, x) = atan2(y, x)

This operator supports in-place execution, meaning that the output tensor is permitted to alias ATensor or BTensor during binding.

Syntax

struct DML_ELEMENT_WISE_ATAN_YX_OPERATOR_DESC {
  const DML_TENSOR_DESC *ATensor;
  const DML_TENSOR_DESC *BTensor;
  const DML_TENSOR_DESC *OutputTensor;
};

Members

ATensor

Type: const DML_TENSOR_DESC*

The input tensor to read the Y-axis values from.

BTensor

Type: const DML_TENSOR_DESC*

The input tensor to read the X-axis values from.

OutputTensor

Type: const DML_TENSOR_DESC*

The output tensor to write the results to.

Remarks

Availability

This operator was introduced in DML_FEATURE_LEVEL_3_1.

Tensor constraints

ATensor, BTensor, and OutputTensor must have the same DataType, DimensionCount, and Sizes.

Tensor support
