code

说明：  主要是matlab7.0在数字信号处理中的应用，仅供初学者看，本人是菜鸟级人物。(Mainly matlab7.0 in digital signal processing applications, only a beginner, I was the rookie-level characters.)

svm分类器，有几类样本点，利用线性SVM分类器求出其分界面(svm classifier, there are several types of sample points, using a linear SVM classifier obtained the sub-interface)

时间序列的一般分解实例，其中包括原始数据，季节项，趋势项和随机项(General time series decomposition instance, including raw data, seasonal items, the tendency and random items)

Normal ECG test taken on 250 Hz (sampling frequency) You can use in order to obtain (and compare) the stress (from HRV) (compare with ecg stroop & ecg matematica )

语音去噪LMS自适应滤波算法,利用LMS自适应滤波算法进行语音去噪(Speech Denoising LMS adaptive filtering algorithm, using LMS adaptive filtering algorithm for voice denoising)

Canny邊緣檢測的函數 a: input image sigma: Gaussian的均方差

用matlab的mesh命令画出所要求解的大量数据文件的图形(The mesh command using matlab draw large amounts of data required for solution of graphic files)

该代码基于灰色GM(1,1)算法，使用时，需要在函数中将自变量取为时间序列，可预测任意时间的数值(The code is based on gray GM (1,1) algorithm, when used in the function argument will be taken as time series, can predict the value of any time)

在matlab绘图中绘制不同函数曲线的用户界面的m函数，奉献给大家！(Drawing graphics in matlab function curves of different user interface function of m, and dedication to you!)
