Solving the j-th column? are there more detailed clue of this?

Yeah. Actually I only care about the several elements in the inverse

matrix. The first thing pop up in my mind is Cramer's Rule. It seems

it is too naive to carry on.

Are there better way to obtain these values without going through the

whole LUD?

Consider solving the jth column of the equation X*X^-1=I for suitable

value of j.
