I'm trying to make video out of the function that suppose to generate 234 plot (Ro by GammamaxB) but it keeps telling me that Frame must be 370 by 326.
How can fix it...........
vidObj = VideoWriter('peaks123.avi');
open(vidObj);
for Ro = 0.05:0.05:0.45;
for GammamaxB = 0.5:0.1:3;
skyMap_i(Ro,GammamaxB);
set(gca, 'nextplot','replacechildren');
currFrame = getframe;
writeVideo(vidObj,currFrame);
end
end
% close(gcf)
%# save as AVI file, and open it using system video player
close(vidObj);

Toyese - what keeps telling you that the frame must be 370x326? Please copy and paste the full error message into this question.
Also, what is skyMap_i?

This is the function
function Phi = skyMap_i(Ro,GammamaxB)
PA = [];
irange = 20:5:90;
filename = ['Name_R',num2str(Ro),'_B',num2str(GammamaxB),'_ii', num2str(20),'.dat'];
LC = dlmread(filename, ' ');
prange = LC(:,1);
for ii = irange
filename = ['Name_R',num2str(Ro),'_B',num2str(GammamaxB),'_ii', num2str(ii),'.dat'];
LC = dlmread(filename, ' ');
PA = [PA; LC(:,2)'];
end
figure
[p_f,i_f] = meshgrid(prange,irange);
[c,c] = contourf(p_f/(2*pi),i_f,PA,60);
colorbar
title(strcat('Ro= ',num2str(Ro),',',' \beta_{Max}= ',num2str(GammamaxB)),'Fontsize',20,'Fontweight','Bold')
xlabel('Orbital phase','Fontsize',20,'Fontweight','Bold')
set(c,'linewidth',2,'linestyle','none')
ylabel('Inclination angle i (degrees)','Fontsize',20,'Fontweight','Bold')
This is the error message
??? Error using ==> VideoWriter.VideoWriter>VideoWriter.writeVideo at 327 Frame must be 370 by 326
Error in ==> Plot_ContourVideo at 8 writeVideo(vidObj,currFrame);

For some reason, I think your image has changed size during the loop. Put this in the loop right after you call getframe:
size(currFrame) % Don't use a semi colon
Tell me what you see in the command window.
See attached demo where I make a movie from a changing/moving surface in a figure.
