writing a file
显示 更早的评论
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

Hi Kash,
this is more or less the same question as
http://www.mathworks.com/matlabcentral/answers/25354-error-in-writing-function-file
Perhaps we continue the discussion there ...

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)
