  • Ticket #18640 – Description

    initial v1  
    1111  (Parent class)
    1212- `ScalarField`: scalar field M --> K (Element class)
     13- `ExpressionNice`: a subclass of `sage.symbolic.expression.Expression` with enhanced display of callable symbolic expressions
     14
    1315Internally, `ScalarField`'s are described by their coordinate representations in various charts, which are implemented as a dictionary of `CoordFunction`'s, with the charts as keys.
    1416At the moment, there is only one concrete class for coordinate functions: `CoordFunctionSymb` (functions described by symbolic expressions of the coordinates), but in the future there should be numerical coordinate functions (hence the abstract base class `CoordFunction`).
