WebSuppose we have a system of n linear equations in m variables, and that the n m matrix A is the coe cient matrix of this system. Then 1.We have rank(A) n and rank(A) m, because there cannot be more pivots than there are rows, nor than there are columns. 2.If the system of equations is inconsistent, then rank(A) < n. This is because in row- WebLinear Algebra Concept Consistent and Inconsistent Linear Systems Linear Algebra Definition Linear Combination Linear Algebra Definition Linear Independence ...
