Nonzero rows appear above the zero rows. 2. In any nonzero row, the rst nonzero entry is a one (called the leading one). 3. The leading one in a nonzero row appears to the left of the leading one in any lower row. 1

WebInserting the rows in the last equation we get ( c1 c2 3c1 −c2 −2c1 +2c2) = ( 0 0 0 0 ). This gives us c1 = c2 = 0, so the rows are linearly independent. Since they also span the row space of A, they form a basis for the row space of A. This is a general fact: Theorem 1.1 The nonzero rows in U, the reduced row echelon form of a WebEnter A.row(0) to get the rst row of A, or A.row(1) to get the second row. Python’s indexing always starts with 0, so many things need to be shifted by 1 compared to how they are in the notes or in Maple. Similarly, you can enter A.col(0) or A.col(1) or A.col(2) to extract one of the columns of A. To get the top right entry in A(which is called A
