Find a basis for the row space of a

WebElementary row operations do not affect the nullspace or the row space of the matrix. Hence, given a matrix \(A\), first transform it to a matrix \(R\) in reduced row-echelon form using elementary row operations. Then find a basis for the row space of \(R\). It will then be a basis for the row space of \(A\). What about the column space? WebTo find a basis for the row space of A we could proceed in two ways: Method 1 for finding a basis for the row space of A: We need to understand any linear relations that hold among the rows of A. We could take these row vectors and put them into a matrix as columns and proceed as above:
