class Expr< T >
template class to mark template expressions.
- The following classes are a small framework to help building classes for automatic differentiation towards multiple variables. Expressions that operate on these classes are implemented with template expressions
- The basic type on which all operations have place is the template Jacobian<..> Instances of Jacobian<T> store a value of type T and n values for the derivative of elements of type T.
- This template class marks template expressions. Other template definitions can use this mark to detect a template expression and act accordingly.
The Type T should have type definitions valueType and derivType. The underlying type will be an expression or the base type Jacobian<..>
