wave propagation grape code

I want to see graph about wave propagation at -6<x<6,-6<z<6 and t=0,4,8,12,16 information of the wave propagation(y propagation plane wave) : E(x,z,t)= cos(2*pi*10^8+1.05x+1.8z) how can i get the code of graph i want to see? That's all. thank you.

There is no 't' involved in E...

[KSSV]

N = 100 ;
x = linspace(-6,6,N) ;
z = linspace(-6,6,N) ;
[X,Z] = meshgrid(x,z) ;
t = [0 4 8 12] ;
E = zeros(N,N,length(t)) ;
for i = 1:length(t)
    E(:,:,i)= cos(2*pi*10^8*t(i)+1.05*X+1.8*Z) ;
    surf(X,Z,E(:,:,i)) ;
    view(2)
    drawnow
end

oh thank you! i have a question. does the code'view(2)' mean 't=2?'

[KSSV]

You remove view(2) and see how the out put would be.
