DML_ELEMENT_WISE_SIGN_OPERATOR_DESC structure (directml.h)

Returns a value representing the sign of each element of InputTensor, placing the result into the corresponding element of OutputTensor.

f(x) = -1, if x < 0
        1, if x > 0
        0, otherwise // This includes negative zero.

This operator supports in-place execution, meaning that OutputTensor is permitted to alias InputTensor during binding.

Syntax

struct DML_ELEMENT_WISE_SIGN_OPERATOR_DESC {
  const DML_TENSOR_DESC *InputTensor;
  const DML_TENSOR_DESC *OutputTensor;
};

Members

InputTensor

Type: const DML_TENSOR_DESC*

The input tensor to read 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_2_0.

Tensor constraints
