matlab plot uniform distribution

Hi everyone,

I want to plot the theoretical uniform and normal distribution by using surf() in Matlab.

Can anyone help me to approach it?
 

Hey,

surf() is used to draw 3D surfaces in space, the uniform distribution can be drawn by only the 2D plot, so I think you mean you want it to be something like
z=(1/2πσ²)exp-((x²+y²)/2πσ²)

So it'll be this way for σ=0.3:

sigma=0.3;
X=-10:0.5:10;
Y=-10:0.5:10;
[x,y]=meshgrid(X,Y);
z=(1/2*pi*(sigma^2).*exp(-1.*((x.^2)+(y.^2))/(2*pi*(sigma^2))));
surf(x,y,z);
