使用于机械最优化设计课程的检索优化方法的最速下降法(Optimized for use in mechanical retri method optimized design courses steepest descent method)

用SVM进行声音分类的程序，自己编的，效果挺好，用的是libsvm工具箱(With the sound of SVM classification procedures, own, and the effect is very good, with the libsvm toolbox)

应用小区域方差对比，程序简单，利用贝叶斯原理估计混合logit模型的参数，欢迎大家下载学习。( Application of small area variance comparison, simple procedures, Bayesian parameter estimation principle mixed logit model, Welcome to download the study.)

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)
