a program that graphs the Zeros and Poles of a transfer function.

In telecommunications, direct-sequence spread spectrum (DSSS) is a modulation technique. As with other spread spectrum technologies, the transmitted signal takes up more bandwidth than the information signal that modulates the carrier or broadcast frequency. The name spread spectrum comes from the fact that the carrier signals occur over the full bandwidth (spectrum) of a device s transmitting frequency.

归一化LMS算法，自己更改参考信号和期望信号(normalized LMS algorithm，change the reference signal and desired signal by yourself)

matlab编写的文本分类的程序，可以对已经分好词的文本进行分类，先自己导入数据，用libsvm中的svm进行分类和预测，特征用tfidf算法，还利用卡方检验进行了特征选择，可自行设定阈值。(matlab prepared text classification program, you can have a good word of text classification, classification and prediction using libsvm in svm, characterized by tfidf algorithm, also used the chi-square test was used for feature selection, you can set thresholds on their own.)

层次分析法！改进的判断矩阵一致性检验 进行矩阵一致性度量的方法主要有两种，一种是由T.L.Saaty提出的一致性比率法C.R.(Consistency Ratio)[13]。还有一种是由Crawford与Williams提出的基于行几何平均法(Row Geometric Mean Method)的几何一致性指标GCI(Geometric Consistency Index)[14]。我们采用的是第一种方法：一致性比率法(C.R.)。(The analytic hierarchy process! Judgment matrix consistency test improved)
