Webb) If the system has strictly fewer equations than unknowns it has either no solution or an in nite number of solutions. Proof. First prove statement a): Let A be the augmented matrix of the system. If this matrix is n (m + 1), then that means the system has n equations and m unknowns. As the system has a unique solution, rref(A) cannot have a ... In linear algebra, a matrix is in echelon form if it has the shape resulting from a Gaussian elimination. A matrix being in row echelon form means that Gaussian elimination has operated on the rows, and column echelon form means that Gaussian elimination has operated on the columns. In other words, a matrix is in column echelon form if its transpose is in row echelon form. Therefore, only …
