I want to classify my image files into 4 classes, but I only get 0 and 1 with this code:
Target_Data = ones(1,Total_Images);
Target_Data(1:Total_Images/4) = 0;
How to add the other classes? Thank you.

May be you are confusing with logical indexing, there is nothing related to classification of images
lets say Total_Images=8, that menas Target_Data= ones(1,8)
>> Target_Data=ones(1,Total_Images)
Target_Data =
1 1 1 1 1 1 1 1
in next line Total_Images/4=2, so the next line is Target_Data(1:2)=0
>> Target_Data(1:Total_Images/4)=0
Target_Data =
0 0 1 1 1 1 1 1
It is checking the 1 D array elements from 1 to 2 (Target_Data(1:2)) equal to zero or not, its false logic, therefore it is zero,
There for 1st and 2nd elements are 0 and rest are same as initial Taret__Data.
If you do following one, lets check all Target_Data elemets, wheather 0 or not, you may get all zero in resultant target elements.
>> Target_Data(1:8)=0
Target_Data =
0 0 0 0 0 0 0 0
I didnot find any clue to classes images based on these two statements, if you can, as you now undestand the code, do modification accordingly.
