Unit triangular matrix where all the diagonal are one. A lower triangular matrix is unit lower triangular if it has ones on the diagonal and each and every element above the diagonal element is zero. Unit lower triangular matrix is of the form: A = $\begin{bmatrix}1 & 0 &0 & . & . & 0\\a_{21}& 1 & 0 & .
The rule for matrix multiplication, however, is that two matrices can be multiplied only when the number of columns in the first equals the number of rows in the second. A major application of matrices is to represent linear transformations, that is, generalizations of linear functions such as f(x) = 4x. square matrix is a matrix with the same number of rows and columns. An n-by-n matrix is known as a square matrix of order n. Any two square matrices of the same order can be added and multiplied. The entries a ii form the main diagonal of a square matrix.
