public IExpr evaluate(IAST ast, EvalEngine engine)
AbstractFunctionEvaluatorast.get(0) (or alternatively ast.head()) contains the
head (i.e. the function symbol) of this abstract syntax tree (AST). ast.arg1() to ast.get(n) the ast contains the first to n-th argument of the
function (alternatively you get the first to fifth argument with the methods arg1(), arg2(),...
arg5()).Validate class to check the number or types of arguments in the evaluate
