Reduced row echelon form (rref) can be used to find the inverse of a matrix, or solve systems of equations. student.desmos.com . It makes the lives of people who use matrices easier. 1/ To assess whether a matrix is invertible and finally find its reverse: whenever you use the basic operations to a matrix so as to set it in the low echelon form you're really multiplying it with a pair of matrices P1, P2,...Pn if the result matrix is the identity so it's possible to state that the matrix is invertible along with the reverse matrix is P1*P2*...*Pn, else it is not invertible. Classroom Activities. A matrix is in row echelon form if all zero rows are at the bottom of matrix, the leading entry of each nonzero row after the first occurs to the right of the leading entry of the previous row, the leading entry in any nonzero row is 1 and all entries in the column above and below a leading 1 are zero.
