Linear Algebraic Equations Part 3

Linear Algebraic Equations Part 3. An equation of the form ax+by+c=0 or equivalently ax+by=-c is called a linear equation in x and y variables. ax+by+cz=d is a linear equation in three variables, x, y , and z . Thus, a linear equation in n variables is

CS 584

CS 584. Iterative Methods. Gaussian elimination is considered to be a direct method to solve a system. An indirect method produces a sequence of values that converges to the solution of the system. Computation is halted in an indirect algorithm when when a specified accuracy is reached.
