Abstract: An iterative algorithm to solve Algebraic Riccati Equations with an indefinite quadratic term is proposed. The global convergence and local quadratic rate of convergence of the algorithm are ...

Ancient Mesopotamian scribes solved the world’s first recorded algebraic equation on clay tablets. Their methods laid the foundation for symbolic mathematics and influenced many modern sciences.

Abstract: This paper develops several new dynamical designs, based on the gradient neural network (GNN), from the perspective of control theory to solve the time-varying Sylvester equation (TVSE). We ...

LARUE COUNTY, Ky. — A Kentucky school district is taking a state law limiting cellphone use in classrooms a step further, creating a weekly screen-free class. While his classmates solved the quadratic ...

We need a utility to calculate roots of a Quadratic Equalition. If D > 0: x1 = (-b + sqrt(D)) / (2a) x2 = (-b - sqrt(D)) / (2a) If D = 0: x = -b / (2a) If D < 0: indicate no real roots exist (complex ...
