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 .

KK matrix is singular matrix so the results are as being dispalyed as nan.is there anyway for achieving that.

display(disp)
but it would have been easier if you had not used disp as a variable name.
