ptypy.utils.math_utils.gaussian2D(size, std_x=1.0, std_y=1.0, off_x=0.0, off_y=0.0)

Evaluates normalized 2D gaussian on array of dimension size. Origin of coordinate system is in the center of the array.

Parameters:

• size (int) – length of requested array

• std_x (float,optional) – Standard deviation in x direction

• std_y (float,optional) – Standard deviation in y direction

• off_x (float, optional) – Offset / shift in x direction

• off_y (float, optional) – Offset / shift in y direction
