SpletThe formal version of this intuition is the rank-nullity theorem. Here it is stated in matrix form: Let A A be an m\times n m× n matrix. Then \text {dim} (\text {ker} (A)) + \text {rank} (A) = n. dim(ker(A)) +rank(A) = n. Here the rank of A A is the dimension of the column space (or row space) of A. A. SpletAnswer (1 of 6): Row reduce to echelon form. * rank = # of nonzero rows in echelon form (also dimension of row space and dimension of column space) * nullity = dimension of …
