Hi,

I'm trying to plot 2 lines using the mesh function,

This is what I hoping to achieve. This example graph has 45 lines.

I don't really know what to do, if I import the data as column vectors like this:

x = load('x.txt.'); y1 = load('y1.txt.'); y2 = load('y2.txt.');

Could somebody advise me what the command would be to plot them using the mesh function.

I've searched online but cannot find an example similar to this. I just need to be pointed in the right direction.

Thank you

In the simplest case you have some data

M = 2; N = 10; x = 1:N; y = 1:M; z = randn(M, N);

and you create a mesh

mesh(x, y, z);

For you, assuming the text files are the correct sizes ...

M = 2; y = 1:M;

x = load('x.txt'); N = length(x);

z = zeros(M, N); for ii = 1:M z(ii, :) = load(['y', num2str(ii), '.txt']); end

Instead of mesh maybe you want

plot3(x, y'*ones(1, N), z)

I edited my question to include a plot3 option. Is that more what you are looking for?
