Dewdrop - are you referring to the disp variable? I ran your code and didn't see where it is being set (or displayed?) as NaN. By the way, I suggest that you rename this variable so that it does not conflict with the built-in MATLAB function of the same name.

rank(kk) is only 4, when it would need to be 12 .

kk has a number of rows that are all zero

Could you confirm that your bdcof variable is intended to be different than your bcodf variable? I get the impression that bcodf is a persistent typing mistake for bdcof .
