It is used to construct LEL objects that represent scalars constants. They can be of type Float,Double,Complex,DComplex and Bool. A description of the implementation details of the LEL classes can be found in Note 216 Example Examples are not very useful as the user would never use these classes directly. Look in LatticeExprNode.cc to see how it invokes these classes. True Motivation Constants are a basic mathematical expression.
Constructor takes a scalar.
This throws an exception, since only a scalar can be returned. This derived LEL letter class handles numerical unary operators Synopsis This LEL letter class is derived from LELInterface. It is used to construct LEL objects that apply numerical unary operators to Lattice expressions. A description of the implementation details of the LEL classes can be found in Note 216 Example Examples are not very useful as the user would never use these classes directly. Look in LatticeExprNode.cc to see how it invokes these classes.
