随机性的NIST测试matlab程序，包含十五种测试指标，功能齐全！(The NIST test for randomness,it contains fifteen tests.)

实现任意多个麦克风阵列的波束形成，麦克风阵列可以是加性的，也可以是差分的；阵列是均匀线阵，波束图经过线性归一化。(The microphone array can be additive or differential, and the array is uniform linear array, and the beam pattern is linearly normalized.)

hide text files using simple encryption algorithnm in matlab

一个挺好的PCA例子，粗学者可以试试看，很有帮助的(pca exam)

把加速度信号变为速度信号和位移信号。用的是反频谱法(Acceleration signal into a displacement signal)

说明：  Matlab 模拟 CDMA 直接扩频。m序列生成矩阵为p(x) = 1 + x^5 + x^7 + x^8 + x^9 + x^13 + x^15。能画出每阶段的时域、频域图。(Matlab simulation of CDMA Direct Spread Spectrum. m sequence generated matrix for p (x) = 1+ x ^ 5+ x ^ 7+ x ^ 8+ x ^ 9+ x ^ 13+ x ^ 15. To draw each stage of the time domain, frequency domain Fig.)
