DML_ELEMENT_WISE_LOGICAL_EQUALS_OPERATOR_DESC structure (directml.h)

  • Article

Performs a logical equals on each pair of corresponding elements of the input tensors, placing the result (1 for true, 0 for false) into the corresponding element of OutputTensor.

f(a, b) = (a == b)

Syntax

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

Members

ATensor

Type: const DML_TENSOR_DESC*

A tensor containing the left-hand side inputs.

BTensor

Type: const DML_TENSOR_DESC*

A tensor containing the right-hand side inputs.

OutputTensor

Type: const DML_TENSOR_DESC*

The output tensor to write the results to.

Availability

This operator was introduced in DML_FEATURE_LEVEL_1_0.

Tensor constraints

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