Using contourf with 1D data

Hi, I need to plot data in a polar projection using something like contourf. I have three 1D vectors something like as follows:
if true
% code
end
x = rand(1,10);
y = rand(1,10);
contourf(x,y,z);
if true
% code
end
This gives an error as z needs to be 2D, anyone know how I can reshqape z to suit padding everywhere else with zeros???

I don't really understand what you want to do. Why do you want to show a vector as 2D data???? Especially with random x and y... Anyway, you could pad zeros with paddarray (if you have de image processing toolbox). Otherwise, you could also use this:
z_padded = zeros(10);
z_padded(:,1) = z;
