pathname ='D:\dataset\' ;
dirlist = dir( [pathname '*.jpg'] );
pickind='jpg';
for x = 1:length(dirlist)
I = imread([pathname, dirlist(x).name]);
I=imresize(I,[256 256]);
size(I)
m = mean(I(:));
I1=double(I);
V = var(double(I(:)));
J = stdfilt(I);
SD = std(double(I(:)));
result=[m V SD];
final_col2{k}=result;
end
save('new','final_col2');
please tell how to write a function file for this and call it in a main file

Please do not start new questions just because no one has answered a previous question. You can post reminders, and you can edit questions to reflect current situations.

Here there is one input in the code which is pathname and your final output is final_col2. So you can make a function as
function FinalOut = MyFunc(InputPath)
pathname = InputPath;
dirlist = dir( [pathname '*.jpg'] );
...
...
...
...
final_col2{k}=result;
end
save('new','final_col2');
FinalOut = final_col2;
end
Also 'final_col2' should be initialized before starting the loop for efficiency purpose.
final_col2=cell(length(dirlist),1)

Hope, your 'main file' is another matlab function or script.
You can call above function as
RetData=MyFunc('D:\dataset\');
If you are not aware of Matlab functions, please see
