cg_operator: Add Operator
In cgraph: Computational Graphs

Description Usage Arguments Value Note Author(s) Examples

Add an operation node to the active graph.

1	cg_operator(fun, inputs, name = NULL)

`fun`	cg_function object, function evaluated by the node.
`inputs`	list, the nodes that are consumed by the operation.
`name`	character scalar, name of the node (optional). In case argument `name` is missing, the node is added to the graph under an automatically generated name.

cg_node object.

Any objects that are supplied to argument inputs that are not cg_node objects are implicitly coerced to cg_constant objects.

The elements of argument input can be named to control how the arguments of the function provided to argument fun are machted when the function is evaluated. In case no names are provided, arguments are matched positionally.

# Initialize a computational graph
graph <- cg_graph()

# Create a custom negation function
f <- cg_function(
    def = function(x) -x,
    grads = list(function(x, val, grad) -grad)
)

# Add a an operator with the negation function to the graph.
a <- cg_operator(f, list(10), name = "a")
