Let X be an affine space over a field k, and V be its associated vector space. An affine transformation is a bijection f from X onto itself that is an affine map; this means that well defines a linear map from V to V; here, as usual, the subtraction of two points denotes the free vector from the second one to the first one, and "well-defined" means that implies that If the dimension of X is at least two, a semiaffine transformation f of X is a bijection from X onto i… WebJan 29, 2015 · Forgetting about affine transforms for a minute, in general, when you're solving Ax = b, you want the solution inv(A)*b.
