the first row and elementary row operations to transform all elements under the pivot to become zeros. Step Consider the next row as first row and perform steps and with the rows below this row only. Repeat the step until all rows are exhausted. - - Applications of Matrices and Determinants Example .
Reduce the matrix to a row-echelon form. Note R / This is also a row-echelon form of the given matrix. So, a row-echelon form of a matrix is not necessarily unique. Example .
