Find rref of a matrix

❖ Do RREF for 3 by 3 matrix, so we have transformed matrix to Reduced Row Echelon Form. The size of the matrix we have chosen for this video 3x3 matrix. The size of matrices is sometimes called order or dimension.

❖ A basic introduction into the reduced row echelon form and the steps of this elimination for matrices is presented in this precalculus tutorial. This method is a process used to solve a system of linear equations by converting a matrix into a reduced row echelon form matrix by using elementary row operations and we have used different sizes of matrices.
