Matlab smooth a 3d mesh plot

Question

Hi I have a set of data A with each element corresponding to an x and y combination. When I plot this dat using mesh I get a graph with many spikes on it. This is not unnexpected but I would like a way to smooth these out to get a smooth surface. I've tried to use the smooth3 command but cannot figure out how to make the suitable input. Any help would be appreciated. Thanks

This is how my data is generated.

function v = f(x,y) % Not actual function
return x*rand()+y*rand()
end

x = 0.05:0.01:0.95;
y = 0.05:0.01:0.95;

o = zeros(length(x),length(y));
A = zeros(length(x), length(y));
for k = 1:5
    for i = 1:length(x)
        for j = 1:length(y)
            o(i,j) = f([x(i), y(j)]);
        end
    end
    A= A+o;
end
A = A/5;

This is what produces the plot.

[X,Y] = meshgrid(x);
mesh(A)

my be you can try a convolution of your variable A with a filter(the following is an example of a Gaussian filter).

C = conv2(A,fspecial('gaussian', hsize, sigma)); check conv2 and fspecial in matlab help
