problem of 2d PDE animation

although i sucessfuly find out the solution of the hyperbolic PDE, the surface are not the hot in colormap, is there any wrong order in my code on colormap('hot)'?otherwise,the colormap are only suitable for a graph but not a movie?

g = 'squareg';
b = 'squareb3';
c=1;d=1;a=0;f=0;
[p,e,t]=initmesh(g);
x=p(1,:).';y=p(2,:).';
u0=atan(cos(pi*x));
ut0 = sin(cos(pi*y/3));
nframe = 200;
tlist = linspace(0,5,nframe);
u1 = hyperbolic(u0,ut0,tlist,b,p,e,t,c,a,f,d);

pdeplot(p,[],t,'XYData',u1,'ZData',u1,'Colormap','hot')

%for j=1:nframe
%    pdesurf(p,t,u1(:,j));
%    mv(j) =getframe;
%end
%colormap(hot)
%movie(mv,1)

Or simply:

pdesurf(p,t,u1(:,10));
colormap hot
