unrecognized input argument moviegui MATLAB R2015b

Hello, I tried this code:

h=figure;
movegui(h, 'onscreen');
rect = get(h,'Position'); 
rect(1:2) = [0 0]; 
vidObj = VideoWriter('H1,H2.avi');
vidObj.Quality = 100;
open(vidObj);
for it=1:Nt
    t=it*dt;
    H1(1) = 1;  
    figure(1)
    h=plot(x,H1,'--',x, H2,':','lineWidth',2);
    title({['H1 and H2 in the wake region'];['time(\itt) = ',num2str(dt*it)]})
    xlabel('Spatial coordinate (x) \rightarrow')
    ylabel('(H1), (H2) \rightarrow')
    legend('H1', 'H2')
     movegui(h, 'onscreen');
     hold all;

      if ~mod(t,0.1)
          saveas(gcf, ['t=',num2str(t),'.png'])
      end
      for i=2:Nx
         H1(i)=...
      end
  end
  close(vidObj);

Why I cannot see any movie and I get the error message above?

Post the complete error message, such that we do not have to guess which of the 2 movegui commands fails.

movegui(h, pos) requires the first input to be the handle of a figure. But inside the loop h is the handle of the line object created by plot().

Because the figure does not change its size inside the loop, you can omit the movegui command there.

Some improvements:

hFig = figure;  % a better name than simply "h"
...
  figure(hFig);  % Not hardcoded [1]
  ...
  movegui(hFig, 'onscreen');  % Or omit this line!
