Elimination with Matrices - MIT OpenCourseWare
ocw.mit.eduThe elimination matrix used to eliminate the entry in row m column n is denoted Emn. The calculation above took us from A to E21 A. The three elimination steps leading to U were: E32(E31(E21 A)) = U, where E31 = I. Thus E32(E21 A) = U. Matrix multiplication is associative, so we can also write (E32E21)A = U.
Lecture 14: Orthogonal vectors and subspaces
ocw.mit.edudimension n − r dimension m − r Orthogonal vectors Orthogonal is just another word for perpendicular. Two vectors are orthogonal if the angle between them is 90 degrees. If two vectors are orthogonal, they form a right triangle whose hypotenuse is the …
