Detailed Description
Embodiments of the workpiece surface treatment system using numerical analysis according to the present invention will be described in detail below with reference to the accompanying drawings.
In numerical analysis, the direct method finds a solution to the problem using a fixed number of steps. These include gaussian elimination and QR algorithms to solve linear equations, simplex methods to solve linear programming, etc. Some problems can be solved by using infinite precision arithmetic calculation. However, some problems do not have an analytical solution (such as a quintic equation), and cannot be solved by a direct method. In a computer, floating point numbers are used for operation, and under the premise of assuming a stable operation mode, the obtained result can be regarded as an approximate value of an accurate solution.
Iterative methods are mathematical processes that solve the problem by finding a series of approximate solutions from an initial estimate. Unlike the direct method, when the iterative method is used to solve the problem, the steps are not fixed, and only approximate solutions of the problem can be obtained, and a series of the found approximate solutions can converge to an accurate solution of the problem. A convergence method is used to determine whether the obtained approximate solution converges. In general, even with infinite precision arithmetic, iterative methods cannot get an accurate solution to the problem in a limited number of times. There are more cases where iterative methods are used in numerical analysis than direct methods. Such as newton's method, dichotomy, jacobian method, generalized minimum residual method (GMRES), conjugate gradient method, and so forth. In computing matrix algebra, large problems typically require iterative methods to solve.
