Hello, I need to plot H,u at times

t=0.1, 0.2, 0.3, ...1

in the same plot over a range of time. I know below code is wrong but how can I fix it?

 dt=0.01;  
 Nx = 101;
 Nt= 101;
 t=0;
 H=zeros(1, Nx);
 u=zeros(1, Nx);
  for nt=1:Nt   % time loop
  t=(nt-1)*dt;
    for i=1:Nx
    H(i) = ...
    u(i) = ...
    end
    for ntstep=1:10
        t=(ntstep-1)*10*dt;
        newH(ntstep,1:Nx)=H(1:Nx); 
        newu(ntstep,1:Nx)=u(1:Nx); 
    end
end
for i=1:10
    hold on;
    figure (1);
    hplot1 = plot(x,newH(i,1:Nx),'lineWidth',1.3);
    hold on
    hplot1 = plot(x,newu(i,1:Nx),'lineWidth',1.3);
    hold on
end

Hello,

I have changed the code as below:

dt=0.01;  
 Nx = 101;
 Nt= 101;
 t=0;
 H=zeros(1, Nx);
 u=zeros(1, Nx);
  for nt=1:Nt   % time loop
  t=(nt-1)*dt;
    for i=1:Nx
    H(i) = ...
    u(i) = ...
    end
    for k=1:10
        if k*0.1 == nt
           newH(k,1:Nx)=H(1:Nx); 
           newu(k,1:Nx)=u(1:Nx); 
        else
           continue
        end
    end
end
for i=1:10
    hold on;
    figure (1);
    hplot1 = plot(x,newH(i,1:Nx),'lineWidth',1.3);
    hold on
    hplot1 = plot(x,newu(i,1:Nx),'lineWidth',1.3);
    hold on
end
