  +Performs a MatMul followed by a specified series of operations.
  +
  +The inputs to the MatMul are specified by `a` and `b`. The series of operations
  +that follows is specified by the `fused_ops` attribute, which is a list of TF op
  +names specified as strings (e.g. "Relu"). They are performed in order, where the
  +(first) input to each op is the output of the preceding op. The first input and
  +the output of each fused_op must be of type T.
  +
  +Currently supported fused_op combinations are: ["BiasAdd"] and ["BiasAdd",A],
  +where A is one of {"Elu","Relu","Relu6"}.
  +
  +* The first input to BiasAdd is the Conv2D result, and the additional BiasAdd
  +input is specified by `args`.
  +* If there is an op A specified, the output of the BiasAdd is the input to op A,
  +and op A produces the _FusedConv2D output. Otherwise, the BiasAdd produces the
  +_FusedConv2D output.
  +
  *NOTE*: Do not invoke this operator directly in Python. Grappler is
  expected to create these operators.
