在这工作不同类型的神经网络实现的 matlab 代码。

线性代数方程组的求解全选主元高斯消去法全选主元高斯约当消去法复系数方程组的全选主元高斯消去法-linear algebraic equations to solve all the main election yuan Gaussian Elimination entire election PCA about when Gaussian Elimination of complex equations of the entire election PCA Gaussian Elimination Act, etc.

计算方法的一个比较重要的高斯约当消去方法-calculation of a more important about when Gaussian Elimination Methods

问题给定n中物品和一个背包，物品i的重量为wi，价值为vi，背包的总容量为W。要选择装入背包的物品使得装入背包物品的总价值最大。对于每一个物品只有选中放入背包和不选中两种状态，分别用1和0来表示。可将0-1背包问题解空间组织成子集树的形式。以深度优先的方式，由父节点开始搜索整个解空间，将选中的物品价值和重量加到总价值和总重量里面。当遍历所有分支和节点，比较得到问题的最有解和最优值。

Implements Minimum Search Tree using Kruskal Algorithm

这是用C编写的贪婪算法,非常实用,欢迎大家下载哈!-This is prepared by using C greedy algorithm is very practical, welcomed everyone to download Ha!
