◆ jkqtpParametricCurveFunctionType

typedef std::function<QPointF(double, const QVector<double>)> jkqtpParametricCurveFunctionType

type of functions that may be plotted by JKQTPXYFunctionLineGraph

This is the type of functions $ [x,y]=f(t, \vec{p}) $ that may be plottet by JKQTPXYFunctionLineGraph. It is possible to supply parameters $ \vec{p} $ to the function that influence its result. Parameters are given as a pointer to some memory location. The function has to know on its own how to interpret these.

◆ jkqtpPlotFunctionType

typedef std::function<double(double, const QVector<double>&)> jkqtpPlotFunctionType

type of functions that may be plotted by JKQTPXFunctionLineGraph and JKQTPYFunctionLineGraph

This is the type of functions $ y=f(x, \vec{p}) $ that may be plottet by JKQTPXFunctionLineGraph and JKQTPYFunctionLineGraph. It is possible to supply parameters $ \vec{p} $ to the function that influence its result. Parameters are given as a pointer to some memory location. The function has to know on its own how to interpret these.

◆ jkqtpSimpleParametricCurveFunctionType

typedef std::function<QPointF(double)> jkqtpSimpleParametricCurveFunctionType

simplified type of functions (without parameters) that may be plotted by JKQTPXYFunctionLineGraph

This is the type of functions $ [x,y]=f(t) $ that may be plottet by JKQTPXYFunctionLineGraph and JKQTPYFunctionLineGraph.

◆ jkqtpSimplePlotFunctionType

typedef std::function<double(double)> jkqtpSimplePlotFunctionType

simplified type of functions (without parameters) that may be plotted by JKQTPXFunctionLineGraph and JKQTPYFunctionLineGraph

This is the type of functions $ y=f(x) $ that may be plottet by JKQTPXFunctionLineGraph and JKQTPYFunctionLineGraph.
