thanks for your kind help. i have used this code
N = 4;
A = imread('my_img.png');
for ii = 1:N
imwrite(A,strcat('my_new',num2str(ii),'.png'));
end
from link given by you. when i run this code it is saving multiple images but when again i run this, it overwrite the images on previous ones instead creating the new images. so how to do that? thanks

Right now you have a fixed N, in this case N=4 and if you run your code you will save the images to my_new1.png, my_new2.png, and so on. Now if you run the code again, the N stays the same which causes the name to be the same, thats why you are overriting the images. If you want to save multiple images in the folder, search for all image files in the folder, count them and then add that number to the name.
From this already answered question ( https://de.mathworks.com/matlabcentral/answers/65564-find-total-number-of-images-in-a-folder ) you can learn how to count the images in a folder.
You can use
a=dir([yourfolder '/*.jpg']); %%You have to give your folder location here
out=size(a,1);
N = 4;
A = imread('my_img.png');
for ii = 1:N
NumberOfNextImage=ii + out;
imwrite(A,strcat('my_new',num2str(NumberOfNextImage),'.png'));
Now your code would check for the total amount of images in the folder and if you run with 4 images and say you already have 12 in the folder, your images would be named ii + 12, so my_img13.png, my_img14.png, ... and so on.

i am saving images in F drive, not in C and i already saved images in F drive but when i use this code then it is showing this error. see the code:
a=dir(['F:\kinect data\color\plant' '/*.jpg']); out=size(a,1);
N = 4; for ii = 1:N NumberOfNextImage=ii + out; imwrite(color,strcat('my_new',num2str(NumberOfNextImage),'.jpg')); end
