ramp generator program and IFOC

在原有matlab程序的基础上增加一个功能即原有程序在未统计之前，一个数默认频次为一，但是这个可以在频次不为1的情况下统计总的频次(Add a function on the basis of the original matlab program that is not before the original program statistics, a number of default frequency is one, but this can count the total frequency in the frequency is not a case)

分析了该信号的时域、频域、倒谱，循环谱等,有较好的参考价值，考虑雨衰 阴影 和多径影响。( Analysis of the signal time domain, frequency domain, cepstrum, cyclic spectrum, etc. There are good reference value, Consider shadow rain attenuation and multipath effect.)

说明：  广义预测控制应用于预测控制，可以根据个人需要进行变换(GPC)

模式识别中统计模式识别的方法,包括贝叶斯，统计学习，LDA，PCA，SVM的经典方法，是不可多得的算法的toolbox(pattern recognition statistical pattern recognition methods, including Bayesian statistics study, LDA, PCA, SVM classical method, the algorithm is rare in toolbox)

matlab实现的DTMF,可以产生DTMF信号然后识别出来。(matlab realized DTMF, can generate DTMF signals and then identified.)
