Part 6: Finding the Nullspace: Solving Ax = 0 by Elimination

Om kurset

Description This new video computes the nullspace of any matrix A. The equation Ax = 0 is reduced to row echelon form Rx = 0. Then all solution vectors are combinations of “special solutions”. We understand the pieces of R from the factorization A = CR.
