Linear transformation n-dim to m-dim
Description:
Explore the geometric interpretation of linear equation systems in this comprehensive lecture from the Wild Linear Algebra series. Delve into the association between m equations in n variables, m by n matrices, and linear transformations. Gain insights into solution existence and characteristics through kernel and rank concepts. Discover a novel approach to subspaces using properties rather than infinite sets, aligning with modern computer science. Examine illustrative examples covering various dimensions, linear transformations, and subspace properties. Learn about kernel and image properties, hyperplanes, and spanning sets. Engage with theorems, proofs, and exercises to solidify understanding of these fundamental linear algebra concepts.
