I am using 'surf' to create a 3D surface plot. However, the color in the plot does not match what is shown in color bar. Here is the code, please help.
if true
r = (1:0.01:3);
m = length(r);
theta = linspace(0,2*pi,721);
n = length(theta);
for i=1:m
for j=1:n
x(i,j) = r(i)*cos(theta(j));
y(i,j) = r(i)*sin(theta(j));
z(i,j) = r(i)^2;
end
end
surf(x,y,z)
colorbar
end

The color does match when I run it in R2017a, and use mesh instead of surf to do the plot.
