Function Step

The Function section contains the following elements.

Insert

Creates a new node and opens the "Edit Node" window where you can edit the new node.

If an existing node is selected when you click on Insert, the new node is added before the selected node.

Note
It is allowed to add an invalid expression as a placeholder. You can add an expression that does not make sense within the first node used and will make sense later. See Node transferFcn in Demo Project Function Closed-Loop (PID) as example:

Delete

Deletes the selected node(s).

Edit

Opens the "Edit Node" window where you can edit the selected node.

Note
You can also double-click to edit a node

Validate All

Checks the validity of all nodes.

Symbolic Regression

"Symbolic Regression" window opens where you can define settings for symbolic regression analysis.

The button opens a drop-down where you can create a new symbolic regression or open previous results.If you want to remove previous results out of the list, you have to open the result and select "Delete Result" in the "Symbolic Regression" window. The function node itself is not affected of this operation.

Dependency Graph

Opens theDependency Graph for Function <Name> where you can see the graphical representation of the function and analyze dependencies of nodes. The function is visualized as a data flow graph.

Function Nodes table

This table lists all existing nodes of the function or subfunction selected in the "Functions" list. The New row at the bottom can be used to create a new node.

"Functions" list

This list shows the main function and the subfunctions. You can use the buttons below the list to Add, Edit, or Delete a selected subfunction.

Import Functions

Imports a function from a text file. See also Exporting and Importing Functions.

Export Functions

Exports the main function and all subfunctions to an export text file (*.mocafun). See also Exporting and Importing Functions.

Edit Mode option

If the Edit Mode option is activated, you can change the elements of the function directly in the Function Nodes table. The names of data, parameters and nodes are marked with %.

Note
Syntax Highlighting with different colors for Node, Input, Parameter, Model or Sub-Function (see Legend).
