VC和Matlab的扩展编程

支持公历、农历及公历转农历使用公式法（不是查表法）的日历控件，完全自主开发。- A fair experience, the lunar calendar and the male experience transfer the lunar calendar use formula law (is not Zha Biaofa) the calendar controls, completely independently develops.

这是一个面波正演示 matlab程序代码，适合初学者者使用，地球物理学中正演去噪的常用手段

算法过程：1).读入数据，将数据用user_brands存起来，同时建立userid_id，再建立id_brands  2).遍历id_brands得到物品-用户倒排表brand_ids，根据倒排表得到用户的相似矩阵sim_mat  3).为每个用户推荐产品：      3.1).求用户u买过的brand和所有brand的差集得到用户u没有买过的物品集合brand_unused；      3.2).用户u对每一个没用过的物品i的兴趣p(u,i)：          3.2.1).找到与用户u最近的k个用户          对于每一个没用过的物品i：          3.2.2).找出这k个用户中对物品i有过行为的用户v[]√          3.2.3).将用户u和v[j]的兴趣相似度累加      3.3).取前m个最感兴趣的brand推荐给用户；  代码：UCF.cc（用户协同过滤核心代码）：#include  #include  #include  #include  #include  #include  #include  #include  #include  #include  

指派问题的匈牙利算法（matlab语言）-assignment of the Hungarian algorithm (Matlab language)

％ [nearest_neighbours] = find_nearest_neighbours( database, desc, max_dist ) ％ Find the indices of the nearest neighbours of the given desriptors in the近邻点寻找算法，在非线性时间序列中很有用，是常用的算法- [Nearest_neighbours] = find_nearest_neighbours (database, desc, max_dist) Find the indices of the nearest neighbours of the given desriptors in the neighbor-point search algorithm, the nonlinear time series of very useful, is a commonly used algorithm

This GUI can be used by entering nu at the MATLAB command prompt. The user can either select a function (f(x)) of their choice or a statistical distribution probability distribution function to plot over a user defined range. The function s integral can be evaluated over a user defined range by using: The composite trapezium, simpsons and gauss-legendre rules. This is useful for calculating accurate probabilities that one might see in statistical tables.
