Surface plot form 1d data

I want to make a mesh plot from 1D equation. I have an one-dimensional equation. I want to make a mesh plot with such equation. I am expecting the diagonal of the matrix resulting solution of equation.

%% 1D line plot

x = linspace(0,1000,1000);

C = x.*(1-2/3*x);

figure(1):plot(x,C)

%% create 2D mesh from x-cordinate;

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

%%% how to Convert C to 2D matrix

surf(X,Y,CC)

We have absolutely no idea what result you are expecting.

Try this:

 %% 1D line plot 
x  = linspace(0,1000,1000);
C  = @(x) x.*(1-2/3*x);
figure(1)
plot(x,C(x))
%%  create 2D mesh from x-cordinate;
[X,Y] = meshgrid(x);
%%% how to Convert C to 2D matrix 
surf(X,Y,C(X+Y), 'EdgeColor','none')
