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 & .
In mathematics, a nonnegative matrix is a matrix in which all the elements are equal to or greater than zero. A positive matrix is a matrix in which all the elements are greater than zero. The set of positive matrices is a subset of all non-negative matrices. While such matrices are commonly found, the term is only occasionally used due to the possible confusion with positive-definite matrices, which are different.
