Web† Theorem: If A is an mxn matrix, then the row space and column space of A have the same dimension. † Deﬂnition: The dimension of the row (or column) space of a matrix A is called the rank of A; denoted rank(A). † Example: Let A = 2 4 3 ¡1 2 2 1 3 7 1 8 3 5 Then 2 4 3 ¡1 2 2 1 3 7 1 8 3 5! 2 4 1 ¡1=3 2=3 0 1 1 0 0 0 3 5 Therefore ... Web1 feb. 2024 · Observe that the row vectors of the matrix B are the column vectors of the transpose B T. Note that the size of B T is 3 × 5. In part (a), we showed that the column vectors of any 3 × 5 matrix are linearly dependent. It follows that the column vectors of B T are linearly dependent. Hence the row vectors of B are linearly dependent. WebWhat I meant is that: Let's say I have a 3x5 matrix A, i.e. 3 rows and 5 columns. So, each vector in A belongs to R^3. Now when finding the column space, row space or the null space of A-these are all subspaces of the vector spaces: R^3, R^5 and R^5 respectively.
