FFT

这个是基于独立主成分分析的一个MATLAB语言程序，大家可以下载来看看，希望有帮助(This is based on independent analysis of the principal component of a MATLAB language program, you can download to look at, I hope there is help)

插值算法是一类重要的线性搜索方法，其基本思想是在搜索区间中不断用低次插值多项式来近似目标函数。该程序是用二次插值算法求区间上的无约束最优化解。(Interpolation algorithm is one important class of linear search method, its basic idea is constantly in the search interval with a low polynomial interpolation to approximate the objective function. The program is used quadratic interpolation algorithm for unconstrained interval on optimal to resolve.)

可进行短时平均能量，短时平均幅度，短时平均过零率，短时自相光，短时傅里叶变换的函数,使用方便，(The average energy can be short-term, short-term average rate, the average short-term zero-crossing rate, short-term autocorrelation of light, short-time Fourier transform of the function, easy to use,)

通过改变想要处理的帧，和预测器阶数，对原始语音帧和预测语音帧作一个比较，并作出短时谱和lpc谱，最后作倒谱比较。(By changing the processing of the desired frame, and the predictor order, the original speech frame and the predicted speech frame to make a comparison and to make short-term spectrum and the lpc spectrum, cepstrum last for comparison.)

通过matlab图形进行欧拉角的演示，对于理解欧拉角有很大的帮助。(Matlab graphics through Euler angle presentation, for understanding the Euler angle has a great help.)

自己写的一个计算时频分布的程序,可知指定Cohen类分布类型WVD，CWD，PWVD(Himself wrote a calculation procedure for time-frequency distribution shows the distribution of the type specified Cohen category WVD, CWD, PWVD)
