myset=[1 2 3 4 6];
capacity=6;
passedall=[]
passed=[]
for q = 1:5

    q=q+1
    capacity=6;
    passedall = [passedall passed]; 
    myset= setdiff(myset,passedall);

    for b= 1:5
      if (myset(b) < capacity);

        capacity= capacity - myset(b)
        passed(b) = myset(b)
      end
    end
  end

i get this error:

error: myset(4): out of bound 3
error: called from
    deneme at line 13 column 5

Why i get the out of bound error in this code

Because by the time b equals 4, you've removed enough elements from myset that there are only 3 left and myset(b) is no longer valid. Have you tried debugging your program?

I have no idea what you're trying to do with your code since it's not commented at all. As it is, it doesn't make any sense and probably your loops are not needed. Without an explanation of what you're trying to achieve we can't tell you how to fix it.

Note that
