Differential Maps
This chapter describes real damap and complex cdamap objects as supported by MAD-NG. They are useful abstractions to represent non-linear parametric multivariate differential maps, i.e. Diffeomorphisms, Vector Fields, Exponential Maps and Lie Derivative. The module for the differential maps is not exposed, only the contructors are visible from the MAD environment and thus, differential maps are handled directly by their methods or by the generic functions of the same name from the module MAD.gmath. Note that damap and cdamap are defined as C structure for direct compliance with the C API.
