WebModels of various kinds lead to derivatives of 2D Gaussians. Change the orders of the and derivatives and see the forms produced by differentiating a single Gaussian. Contributed by: Stephen Wolfram (March 2011) Open content licensed under CC BY-NC-SA. Webgaussian[x_] := Exp[-x^2] Here there are two di erences from simply saying gaussian = Exp[-x^2]. The rst is the replacement of = with :=, which delays Mathematica’s evaluation of the right-hand side until later, when the gaussian function is actually used. The second di erence is appending [x_] to the name gaussian, indicating that you’re ...
