Public Functions

Grid2D(int xSize, int ySize)#: Constructor with just grid sizes

Grid2D(int xSize, int ySize, double xMin, double xMax, double yMin, double yMax)#: Constructor with grid limits and sizes

virtual ~Grid2D()#: Destructor

void setZero()#: Sets all grid points to zero

double **getArr()#: Returns the reference to the 2D array

double getValue(double x, double y)#: Returns the interpolated value from the 2D grid

double getValueOnGrid(int ix, int iy)#

Returns the interpolated value on grid

Returns the value on grid

void setValue(double value, int ix, int iy)#: Sets the value to the one point of the 2D grid

void binBunch(Bunch *bunch)#: Bins the Bunch into the 2D grid using X and Y coordinates. If bunch has a macrosize particle attribute it will be used.

void binBunch(Bunch *bunch, int ind0, int ind1)#: Bins the Bunch into the 2D grid using coordinate indexes ind0 and ind1. If bunch has a macrosize particle attribute it will be used.

void binValue(double value, double x, double y)#: Bins the value into the 2D grid

void binBunchBilinear(Bunch *bunch)#: Does a bilinear binning scheme on the bunch using X and Y coordinates

void binBunchBilinear(Bunch *bunch, int ind0, int ind1)#: Does a bilinear binning scheme on the bunch using coordinate indexes ind0 and ind1.

void binValueBilinear(double value, double x, double y)#: Bilinear bin of the value into the 2D grid

void calcGradient(double x, double y, double &ex, double &ey)#

Calculates gradient at a position (x,y)

Calculates gradient at a position (x,y) by using 9-points schema

void calcGradient(int iX, int iY, double &ex, double &ey)#

Calculates gradient at a grid point (ix,iy)

Calculates gradient at a grid point (ix,iy) by using 9-points schema

void calcGradientBilinear(double x, double y, double &ex, double &ey)#: Calculates bilinear interpolated gradient at a position (x,y)

void interpolateBilinear(double x, double y, double &value)#

Calculates bilinear interpolation a grid for position (x,y)

Calculates bilinear interpolated value at a position (x,y)

int getSizeX()#: Returns the grid size in x-direction

int getSizeY()#: Returns the grid size in y-direction

void synchronizeMPI(pyORBIT_MPI_Comm *comm)#: synchronizeMPI

int isInside(double x, double y)#: Returns 1 if (x,y) is inside the grid region, and 0 otherwise
