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?
