From what I've read, it seems that explicit numerical matrix inversion is considered a bad idea. However, what if we have an invertible matrix $A$, and find the analytical expression for $A$'s inverse, and then put our numerical values into the analytical expression we just found? Would we be able to attain more stable/accurate results than simply using inv($A$) or would the two simply be exactly equivalent?
