数据预测算法，主要是一元n次方程的回归预测实现。* 预测分析--本算法只适用于有明显线性趋势的数据 * 默认为一元二次曲线方程法 * * 本程序主要涉及有两个算法 * 1．用最小二乘原理找到线性方程组的系数和常数。 * 2．解线性方程组 * 本程序在解线性方程组中，由于考虑到收敛性问题未采用迭代法，而是采用Gauss-Jordan消去法来解决。-data prediction algorithm is mainly one yuan n equation forecast to achieve reunification.* Forecast and Analysis-- This algorithm applies only to clear linear trend data* default as a quadratic curve equation method** The procedure involves two main algorithm* 1. Using the principle of least squares linear equations to find the constants and coefficients.* 2. The solution of linear equations* The procedure for solving linear equations, due to convergence problems using iterative method, instead of using the Gauss-Jordan elimination method to solve.
