DCT_DFT_FFT(matlab)
无限长的序列也往往可以用有限长序列来逼近。对于有限长的序列我们可以使用离散傅立叶变换（DFT）。DFT是对序列傅立叶变换的等距采样。是序列傅立叶变换的等距采样。
本源码是对DCT、DFT、FFT的matlab实现(Infinitely long sequence is often a long sequence with limited approximation. For the finite length of the sequence we can use the discrete Fourier transform (DFT). DFT is a sequence of equidistant sampling Fourier transform. Is a sequence of equidistant sampling Fourier transform. The source is the DCT, DFT, FFT in matlab implementation)

Mersenne-Twister
利用Mersenne Twister算法产生随机数，并测试和分析了其随机性。 程序中还加入了界面显示。
各个文件为：
initGenerator.m：
initGenerator函数，用于初始化随机序列的长度和值
generateNum.m:
generateNum函数，当index为0时被调用，用于创建624维的移位寄存器数组
extractNum.m:
extractNum函数，根据index当前值选择数组中的数生成随机数，同时改变index的值。
main.m:
main主函数，输入种子seed和产生数目total，输出产生结果及随机性测试结果
mymy.m和mymy.fig:
用于界面显示的部分，这两个文件会通过界面传入seed和total的值，并调用main函数，在相应的框中显示输出结果。
(According to the algorithm principle on Wikipedia, the Mersenne Twister algorithm to generate random numbers, and test and analysis of its randomness. The program has also joined the interface display.
The individual files are:
initGenerator.m:
initGenerator function used to initialize the random sequence length and value
generateNum.m:
generateNum function is invoked when the index is zero, and used to create a 624-dimensional shift register array
extractNum.m:
extractNum function, according to index the current value to select the number to generate random numbers, and change the value of the index in the array.
main.m:
main function of the input seed to seed and produce the number of total, the output generated results and the randomness of the test results
mymy.m and mymy.fig:
Part of these two files for interface display interface incoming seed and the total value of, and calls the main function, to display the output in the appropriate boxes.)
