Synopsis

A Function1D is used for classes which map a scalar or n-dimensional Vector of type T into a T. The object also has one parameter which can be masked if necessary, and be used in the Fitting module, and, implicitly, in the AutoDiff differentiation module.

The only method implemented in Function1D is the ndim() method. The rest is inhereted from Function.

Example

See Function.
