Image_Graph_Dataset_VectorFunction:: (7 méthodes):
  Image_Graph_Dataset_VectorFunction()
  addPoint()
  _getPointX()
  _getPointY()
  _reset()
  _stepX()
  _calculateMaxima()

Classe: Image_Graph_Dataset_VectorFunction - X-Ref

Vector Function data set.

Points are generated by calling 2 external functions, fx. x = sin(t) and y =
cos(t)

Image_Graph_Dataset_VectorFunction($minimumT, $maximumT, $functionX, $functionY, $points) X-Ref

Image_Graph_VectorFunctionDataset [Constructor]

param: double $minimumT The minimum value of the vector function variable
param: double $maximumT The maximum value of the vector function variable
param: string $functionX The name of the X function, if must be a single
param: string $functionY The name of the Y function, if must be a single
param: int $points The number of points to create

addPoint($x, $y = false, $ID = false) X-Ref

Add a point to the dataset

param: int $x The X value to add
param: int $y The Y value to add, can be omited
param: var $ID The ID of the point

_getPointX($x) X-Ref

Gets a X point from the dataset

param: var $x The variable to apply the X function to
return: var The X function applied to the X value

_getPointY($x) X-Ref

Gets a Y point from the dataset

param: var $x The variable to apply the Y function to
return: var The Y function applied to the X value

_reset() X-Ref

Reset the intertal dataset pointer

return: var The first T value

_stepX() X-Ref

The interval between 2 adjacent T values

return: var The interval

_calculateMaxima() X-Ref

Calculates the X and Y extrema of the functions
