how to add Custom Function

[Axel Kramer]

You probably mean a Java defined custom function?

Define your function class CustomFunctionClass derived from the IBuiltInSymbol interface hierarchy.

At the start of your program (after F#initSmbols()) define a symbol CustomFunction for your function and assign the CustomFunctionClass as "evaluator"

public final static IBuiltInSymbol CustomFunction= initFinalSymbol(
            Config.PARSER_USE_LOWERCASE_SYMBOLS ? "customfunction" : "CustomFunction");

...
CustomFunction.setEvaluator(new CustomFunctionClass ());
...
