Wolfram`DiagrammaticComputation`
DiagramFunction  |
| returns a pure function whose input/output signature matches the ports of the diagram d | |
▪
The function reads input arguments as the input ports of the diagram, threads them through each subdiagram according to its composition, and returns a tuple of values for the output ports.
▪
Useful for executing a symbolic diagram as code; complementary to , which executes the diagram as a tensor contraction.
