DES
用Matlab实现的DES算法。在Matlab窗口输入DESDECP(a,b,n),其中a，b表示16进制的明文和密钥，n为1表示加密，否则表示加密。(DES algorithm using Matlab. In Matlab window field DESDECP (a, b, n), where a, b indicates a hexadecimal plaintext and key, n is 1 shows an encryption, or that encryption.)

Two_hidden_BPNN
为了对数据进行准确的预测，建立了双隐层BP神经网络，并提供了源数据，实现了准确的数据预测。程序能够执行，误差较小，输出接近真实值。(To accurately forecast the data, we build the two-hidden layer BP neural network and provide the original data, which will forecast the data. The program can be executed with small error which will be close to the real data.)

gender-classification-experiments
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 .

matlab_ipt_tutorial
The purpose of this tutorial is to gain familiarity with MATLAB’s Image Processing
Toolbox. This tutorial does not contain all of the functions available in MATLAB. It is
very useful to go to HelpMATLAB Help in the MATLAB window if you have any
questions not answered by this tutorial. Many of the examples in this tutorial are
modified versions of MATLAB’s help examples. The help tool is especially useful in
image processing applications, since there are numerous filter examples.

Encryption algorithms are becoming
more necessary to ensure data is securely transmitted
over insecure communication channels. FOX is
a recently developed algorithm and its structure is
based on the already proven IDEA (International
Data Encryption Algorithm) cipher.
FOX is a symmetric (private key) block cipher. Its
top-level structure uses the Lai-Massey scheme and
the round functions used in the scheme are substitution
permutation networks (SPN). Its flexibility lies
in the fact that it can be efficiently implemented in
hardware and software. We report some of the first
results of implementing the cipher on an FPGA
