Detailed Description

template<typename T>
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<..>
