- 编程序，按如下要求来求解n元一次线性方程组（假设方程组具有唯一解）。 （1）方程个数n之值由用户通过键盘输入； （2）方程组存放在“增广矩阵”A之中，而n行n+1列的A存储空间通过new来动态分配，且A的各元素值也由用户通过键盘输入； （3）方程组的解存放于“向量”B之中，而具有n个元素的B存储空间也通过new来动态分配。 -programmed by the following demands to solve an n-linear equation (equatio
预测
- 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

- 算法思路： 1.如果只有一个金片，则把该金片从源移动到目标棒，结束。 2.如果有n个金片，则把前n-1个金片移动到辅助的棒，然后把自己移动到目标棒，最后再把前n-1个移动到目标棒. 3.单纯对于有N个金片要挪动的步数求出, 可以使用递推方法,满足递推方程f(i) = f(i - 1) * 2 + 1-Algorithm idea: 1. If there is only a gold film, while the gold from the source to the
