i want to plot Wendland C2 function given by the expression
Z1 = ((1-R).^4*(4.*R+1));
i am using the following lines to plot
[X,Y] = meshgrid(-1:0.01:1);
R = abs(sqrt(X.^2 + Y.^2));
Z1 = ((1-R).^4*(4.*R+1)); %Wendlands C2
surf(X,Y,Z1,'FaceColor','red','EdgeColor','none')
but i cannot plot it correct as shwon in the figure
need some help in this regard

hope fully this will work [X,Y] = meshgrid(-1:0.01:1); R = abs(sqrt(X.^2 + Y.^2)); Z1 = ((1-R).^4.*(4.*R+1)); %Wendlands C2 surf(X,Y,Z1,'FaceColor','red','EdgeColor','none')
