基于matlab 的 dft 的 fft 的 是吸纳(the same as before fft dft )

matlab_Concise tutorial examples希望对大家有所帮助(matlab_Concise tutorial examples)

用于对周期性的数据趋势进行评估与分析，特别适用于具有某个周期的数据组。(For periodic assessment of the data and trend analysis, especially for data having a certain set period.)

北斗二代卫星中37种伪随机码的产生程序代码，可选择几号卫星，生成4ms的伪随机码。(Beidou second generation satellite 37 kinds of pseudo-random code generation program code, you can choose a few satellites, generate 4ms pseudo-random code.)

特征分解型求取离散分数阶傅里叶变换 特征分解算法通过求ＤＦＴ的核矩阵Ｆ（ｋ，ｎ）的特征值 和特征向量构造ＤＦＴ核矩阵的分数幂，以此作为Ｆａ（ｋ，ｎ） 来计算ＤＦｒＦＴ。(The kernel matrix eigenvalue decomposition algorithm for DFT F (k, n) characteristic value And the feature vectors are constructed as the fractional powers of the DFT kernel matrix, which are used as Fa (k, n) To calculate DFrFT.)

说明：  关于瑞利衰落的一段很实用的代码。特别在BPSK调制中对于学习通信方面的同学很有帮助。(Rayleigh fading on a very useful code. BPSK modulation, especially in communications for students to learn helpful.)

代码，关于梯度的HOG特征，挺全的，可以使用(a code about the gradient of the picture)
