这个是一个比较基础的东西，比较适合初学者来学习，同时，最小二乘法是一个很不错的拟合方法(two priority methods-least logarithm square method)

学习matlab的优秀资料，认真研究学习，读者可以从中获得启发，对matlab的学习具有很强的学习意义。(Learning matlab excellent information, serious research study, the reader can derive inspiration, has a strong sense of learning for learning matlab.)

1. 选择一个wav文件作为分析的对象，对该信号进行读取（使用wavread函数）； 2. 音乐信号的频谱分析：首先画出信号的时域波形，然后对信号进行频谱分析得到信号的频谱特性。 3. 设计一组数字滤波器并画出各个滤波器的频率响应 (Filter)

Manual MT4 trading of GPBJPY H1 or H4 very good include template and indicators...

用于分类的主判别变量算法(principal discriminant variate algorithm) ( principal discriminant variate algorithm for two classes, x1 and x2. x1 is the training samples in the 1st class with each column being the spectrum characterizing the corresponding sample. x2 is the training samples in the 2nd class with each column being the spectrum characterizing the corresponding sample. lamda is the penalty weight defining the balance between FLDA and PCA. dvnum is the number of principal discriminant variates to be computed. A defaul value for dvnum is 2. dv is the principal discriminant variates. scores is the matrix with each row being the scores of the samples on the corresponding principal discriminant variate. xmean is the mean spectra of the sample, which was used for mean-centering the data in training and prediction. )
