# Maximum¶

Versioned name: Maximum-1

Category: Arithmetic binary

Short description: Maximum performs element-wise maximum operation with two given tensors applying broadcasting rule specified in the auto_broadcast attribute.

Detailed description As a first step input tensors a and b are broadcasted if their shapes differ. Broadcasting is performed according to auto_broadcast attribute specification. As a second step Maximum operation is computed element-wise on the input tensors a and b according to the formula below:

After broadcasting Maximum does the following with the input tensors a and b:

$o_{i} = max(a_{i},\ b_{i})$

Attributes:

• Description: specifies rules used for auto-broadcasting of input tensors.

• Range of values:

• Type: string

• Default value: “numpy”

• Required: no

Inputs

• 1: A tensor of type T and arbitrary shape. Required.

• 2: A tensor of type T and arbitrary shape. Required.

Outputs

• 1: The result of element-wise maximum operation. A tensor of type T with shape equal to broadcasted shape of two inputs.

Types

• T: any numeric type.
