I am using the imwrite commant for writing the image but i have an error 'you might not have write permission'...How can i resolve it..i am using the following code.
clear cam
cam=webcam;
for i=1:10
A=snapshot(cam);
cam.Resolution='320x240';
imwrite(A,['133MC',num2str(i),'.jpg']);
end
v=VideoWriter('myVideo.avi');
v.FrameRate=2;
open(v)
for i=1:10
K=imreade(['133MC',num2str(i),'.jpg']);

Unable to open file "133MC1.jpg" for writing. You might not have write permission.

The error message is clear: Either the file is existing already and you cannot overwrite it (maybe it is open in another program already), or you do not have write permissions in the current folder. What is the output of
cd
? Use a specified folder:
folder = tempdir;
...
imwrite(A, fullfile(folder, ['133MC',num2str(i),'.jpg']));

It looks like the folder C:\Users\user\Desktop\patch might not exist. You may need to create it if that is where you want your images to be written.
