How to plot multiple arrays in a 3d or surface plot?

Hi,

I plotted my array using the code:

x=[1*1001] vector from 0 to 1;
for nt=1:Nt
    t=0.1+(nt-1)*dt;
    ... 
    u=some vector like [1*1001];
    if abs(t-0.1)<10^(-8)
       u1=u;
    elseif abs(t-0.7)<10^(-8)
       u2=u;
    elseif abs(t-1.2)<10^(-8)
       u3=u;
    elseif abs(t-2.3)<10^(-8)
       u4=u;
       ...
       ...       % Here I have many conditions.
    end
end

plot(x,u1)
hold on
plot(x,u2)
hold on
plot(x,u3)
...            % I have many u** functions to plot!

However, I want to plot all these u** functions versus x and t.

x-axis should be x,

y axis should be t,

and z axis should be u**.

As you see, t conditions are specific. So my t axis should really associated with the correct t value. And u** should be associated with the correct t** value.

use plot3(x,t,u) after using surf with hold on.

Hi KSSV,

I actually used surface and contour. But The graphic is so fine. I need to make grid coarser. I did actually. But it still looks so fine, nothing has changed.

Thanks.
