WebSystems of linear equations are a common and applicable subset of systems of equations. In the case of two variables, these systems can be thought of as lines drawn in two-dimensional space. If all lines converge to a common point, the system is said to be consistent and has a solution at this point of intersection. WebA sparse triangular system of linear equations (STL) is a system of equations of the form Lx = b; (1) where x is the result vector and b is the right-hand side vector, both in Rn, and Lis a lower or upper triangular matrix in R n with a significant number of zeroes. Many algorithms such as those used in managing smart
