Web14 jan. 2024 · Linearly independent means that every row/column cannot be represented by the other rows/columns. Hence it is independent in the matrix. When you convert to RREF form, we look for “pivots” Notice that in this case, you only have one pivot. A pivot is the first non-zero entity in a row. Web5.The columns of Aare linearly independent (as vectors). 6.The rows of Aare linearly independent. If Ahas these properties then it is called non-singular. On the other hand, a matrix that does not have these properties is called singular. Theorem 3 Suppose Ais a square matrix. The following are all equivalent:
