you can generate a mixed string and number name for your image using "sprintf" command. Then use generated names and "imwrite" to save images.

For a = 1:number_of_images

print(['my_figure_nr_' num2str(a)],'fig')

end

you can use these samples for saving your images:

%% saving images in an avi video file

clear;

clc;

for i=1:50

A(:,:,:,i)=uint8(255*rand(500,500,3));

imshow(A(:,:,:,i))

F(i)=getframe;

end

movie2avi(F,'test.avi')

%% saving images in n mat file

clear;

clc;

for i=1:10

B=uint8(255*rand(500,500,3));

save(strcat('A',num2str(i),'.mat'),'B');

end

%% saving images in n image file

clear;

clc;

for i=1:10

A(:,:,:,i)=uint8(255*rand(500,500,3));

imwrite(A(:,:,:,i),strcat('A',num2str(i),'.jpg'),'jpg')

end
