How can I sort Images ?

I have a vector

 norma=[1.087,0.047,0,0.35]

And I have several frames from a video. Ex.

    pill(:,:,:,48);
    pill(:,:,:,49);
    pill(:,:,:,50);
    pill(:,:,:,51);

What I want is to "attach" each frame to each element from norma vector, and then sort the images, by sorting norma vector in ascending way.

How can I do this ?

Thanks in advance !!

Use the second return value of sort to reorder the 4th dimension of your pill array. In your particular example:

norma = [1.087,0.047,0,0.35];
[sortednorma, order] = sort(norma);
pill(:, :, :,  48:51) = pill(:, :, :, 47 + order);
%obviously, if norma is the same length as the 4th dimension of pill, it's simply:
%pill = pill(:, :, :, order);

edit: fixed a typo

norma=[1.087,0.047,0.35]
n=norma'
a=magic(3)
b=cat(2,a,n)
c=sortrows(b,4)
c(:,4)=[];

Should do the job! ofcourse magic will be your video here.
