Create a two dimensional Gaussian window function stored as a matrix.

gausswin_2d(xN, yN, x0, y0, xw, yw)

Arguments

xN

number of pixels in the x dimension.

yN

number of pixels in the y dimension.

x0

centre of window function in the x direction in units of pixels. Note, only integer values are applied.

y0

centre of window function in the y direction in units of pixels. Note, only integer values are applied.

xw

the reciprocal of the standard deviation of the Gaussian window in x direction.

yw

the reciprocal of the standard deviation of the Gaussian window in y direction.

Value

matrix with dimensions fov_yN x fov_xN.
