NAME
       MPSCNNAddGradient

SYNOPSIS
       #import <MPSCNNMath.h>

       Inherits MPSCNNArithmeticGradient.

   Instance Methods
       (nonnull instancetype) - initWithDevice:

   Additional Inherited Members
Detailed Description
       This depends on Metal.framework.  Specifies the addition gradient operator. This arithmetic gradient filter requires the following inputs:
       gradient image from the previous layer (going backwards) and either the primary or the secondary source image from the forward pass. You
       will need a separate filter for the primary and secondary source images.

       Without broadcasting, the arithmetic add gradient operation is a copy operation on the input gradient image. It is the same operation for
       both the primary and secondary source images (for x + y, d/dx(x + y) = 1, d/dy(x + y) = 1). This copy operation can be optimized away by
       the graph interface.

       Setting the broadcasting parameters results in a reduction operation (sum) across all of the applicable broadcasting dimensions (rows,
       columns, feature channels, or any combination thereof) to produce the destination image of the size that matches the primary/secondary
       input images used in the forward pass.

Method Documentation
   - (nonnull instancetype) initWithDevice: (nonnull id< MTLDevice >) device
       Initialize the addition gradient operator.

       Parameters:
	   device The device the filter will run on.

       Returns:
	   A valid MPSCNNAddGradient object or nil, if failure.
