MATLAB: Complementary error function (surf plot)

errorsurf

I'm new to MATLAB and i'm trying to plot the following function with surf:
.
Parameter values:
My code so far:
x = linspace(0,10^(-6),20);
t = linspace(0,5,5);
u0 = 10^(-6); 
k = 10^(-9); 
dn = 2.*k.*sqrt(t);
e2 = erf( x.*(dn).^(-1) );
u = u0.*(1 - e2);  
 
surf(x,t,u)
title('Complementary Error function from 0 to 10^(-6)')
xlabel('Distance x')
ylabel('Time t')
I'm trying to get the x between 0 to in increments of and t in increments of .
How do you fix this?

Best Answer

Add: 
[X,T] = ndgrid(x,t);
and it works: 
x = linspace(0,10^(-6),20);
t = linspace(0,5,5);
[X,T] = ndgrid(x,t);
u0 = 10^(-6); 
k = 10^(-9); 
dn = 2.*k.*sqrt(T);
e2 = erf( X.*(dn).^(-1) );
u = u0.*(1 - e2);  
 
surf(X,T,u)
title('Complementary Error function from 0 to 10^(-6)')
xlabel('Distance x')
ylabel('Time t')
although you may want to revise the code a bit.
