New to programming, I am trying to graph the following Gaussian function in Matlab (should graph in 3 dimensions) but am making some mistakes somewhere. What is wrong?

sigma = 1

for i = 1:20 for j = 1:20 z(i,j) = (1/(2*pi*sigma^2))*exp(-(i^2+j^2)/(2*sigma^2)); end end

surf(z)

However, if I call a .NET method that, in turn, instantiates a Matlab object, it crashes (with a type initialization exception). Think about this scenario: a .NET… >>> More
