Generate 2D Gaussian Distribution — generate_2d

Generates a 2D gaussian distribution, with an optional argument to take the gaussian to a user-defined power.

generate_2d_gaussian(
  sd = 1,
  power = 1,
  dim = c(11, 11),
  width = 3,
  rescale_unity = FALSE
)

Arguments

sd: Default 1. Standard deviation of the normal distribution
power: Default 1. Power to take the distribution. Higher values will result in a sharper peak.
dim: Default c(11, 11). The dimensions of the matrix.
width: Default 3 (-10 to 10). The range in which to compute the distribution.
rescale_unity: Default FALSE. If TRUE, this will rescale the max value to one. Useful if wanting to plot the distribution with plot_image().
