thank i got it...

but the frame picture is at another file. if i place my code in the same folder as the picture

 a = sprintf('Frame %4.4d.png', k);

i can get it when i place it in another file

 a = sprintf('C:\Users\Ren\Desktop\simulation\'Frame %4.4d.png', k);

it is unable to read as after the C: there is a \ is there a way to solve this problem?

a = sprintf('C:\\Users\\Ren\\Desktop\\simulation\\Frame %4.4d.png', k);

Or alternately,

a = sprintf('C:/Users/Ren/Desktop/simulation/Frame %4.4d.png', k);

problem solve thank you...
