Member Function Documentation

virtual const char* ParametricGraph::dependent_var (  int    i )  [inline, protected, virtual]
 

Returns the dependent variable.

The argument 'i' is used to get each dependent variable if there are more than one ( i.e. parametric graph ).

Implements ExpressionGraph.

Definition at line 53 of file parametricgraph.h.

void ParametricGraph::installMathFunctions (    )  [virtual]
 

Implement this function to install any MathFunction's to a specific class.

A math function should be added by calling addMathFunction( MathFunction*, const char * id ) Example: addMathFunction(new DistanceMathFunction(this), "Distance");

Reimplemented from BasicGraph.

Definition at line 85 of file parametricgraph.cpp.
