I have a program ,need to create function file for it,i get error wen i create a function file
path='D:\dataset\'
files=dir(strcat(path,'*.jpg'));
for k=1:numel(files)%numel(files)
file_name=files(k).name;
image_name=strcat(path,file_name);
I=imread(image_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('final_col_new','final_col2');
i wrote function file as
function k=colour1(I)
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
Undefined function or variable "k".

Your function specifies 'k' as an output, yet within the function you use it as an input. There set 'k' as an input in addition to 'I'. Also, you need to determine what the output from your function is - is it 'final_col2'?
