DML_ELEMENT_WISE_SUBTRACT_OPERATOR_DESC structure (directml.h)

  • Article

Subtracts each element of BTensor from the corresponding element of ATensor, placing the result into the corresponding element of OutputTensor.

f(a, b) = a - b

This operator supports in-place execution, meaning that OutputTensor is permitted to alias one of the input tensors during binding.

Syntax

struct DML_ELEMENT_WISE_SUBTRACT_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 DataType, DimensionCount, and Sizes.
