Web23 mei 2024 · 1 Answer. If you really want to find the inverse M of an invertible upper triangular matrix U, note that U M = I M T U T = I, which shows that M T is the inverse of the lower triangular matrix U T. So, you can find M T using the code you already have to invert a lower triangular matrix. This gives you M.
