有关HDB3码型的编码，matlab程序(About the HDB3 code-coding, matlab program)

这是用身高体重数据进行性别分类的实验。 用最小错误率贝叶斯分类器决策时，首先通过比较概率大小判断一个体重身高二维向量代表的人是男是女，然后再逐一与已知性别的数据比较，就可以得到错误率的统计。然后改变先验概率，重复上面的过程，观察数据结果的变化。 用最小风险贝叶斯分类器决策时，首先求出用最小错误率贝叶斯分类器得到的条件概率；然后根据人为给定的决策表，根据公式算出条件风险；然后逐一比较条件风险，找出使条件风险最小的决策（也就是分类）。最后用分类得到的结果逐一比较已经知道的原始数据，统计处错误率。 (This is the height and weight data for gender classification experiment. With the minimum error rate Bayesian classifier decisions , first by comparing the probability of the size and weight to height to determine a person represented by two-dimensional vector is male or female , and then one by one with known gender data comparison, the statistical error rate can be . Then change the prior probability , repeat the above process , the results of the changes observed data . Bayesian classifier with the minimum risk decision-making , first find the minimum error rate using Bayesian classifier to get the conditional probability then artificially given decision table , according to the formula to calculate conditional risk and then one by one more conditional risk , to find ambassador to the conditions of minimum risk decision making (ie classification) . Finally, the results obtained with the classification by-side comparison of the raw data have been aware of SD error rate . )

Including normal voltage voltage voltage sag voltage rise temporarily interrupt voltage shock 6 voltage spike voltage harmonic harmonic harmonic swells sag.)

求最速、牛顿方向的matlab源码，定义函数、初始点，能够得到函数的梯度，海森矩阵，最速下降方向和牛顿方向。

具有丰富的参数选项,基于欧几里得距离的聚类分析，采用了小波去噪的思想，多姿态，多角度，有不同光照,雅克比迭代求解线性方程组课设,采用的是通用的平面波展开法。

此文件夹为七单元线阵的波达方向（music罚法）估计程序，包含不加平滑的估计程序和加上前向平滑的估计程序。程序中每部分都有详细的中文注释，非常容易理解，特别适合于初学者。是本人学习波达方向估计时的心得，希望对大家有帮助。(This folder linear array of seven units of DOA (music Penalty Act) estimation procedures, including without smoothing estimation procedures and smooth with the forward estimates process. Each part of the program are detailed notes in Chinese, is very easy to understand, especially for beginners. DOA estimation is when I am learning experiences, we want to help.)
