Plot surface from different lines

Hi,

I have several plots which are in fact just lines. Now I would like to add these lines to form a surface and create a plot of this surface. How can I do that? Thanks in advance.

From your description, I would use the plot3 function. That is likely as close as you can get to a surface with your lines.

Consider using an interpolation function (for example scatteredInterpolant) to create a complete surface from them.

Hi, thanks for your answer. I have tried but it does not work. Message: Vectors must be the same length. I have tried with plot3(x,y,z) where x=1x50, y=1x6 and z=6x50. Can you help me? Thanks in advance!

In recent MATLAB releases (I’m using R2016b), the mesh and surf functions allow you to use vectors for the independent variables, so you can just do something like this:

The Code:

x = 1:50;                           % Create Data
y = 1:6;                            % Create Data
z = rand(6,50);                     % Create Data

figure(1)
mesh(x, y, z)
