In Response To 'Re: Re: Re: Re: Help with creating matrix from ...' --------- I apologize for my mistakes.
Please describe your rules again for calculating c[[x,y]] that is correct and complete.
Please then give specific examples showing values for x and y in the first row and how to calculate c[[x,y]] that I have calculated zero and you see is incorrect and should be nonzero and show example I have calculated nonzero and you see is incorrect and should be zero. Perhaps two examples will be enough. Perhaps more may be needed so I can see my error.
If I can then understand I will correct my errors.
