it generate triangular membership function for a fuzzy set

设计一个信号发生器,并同时画出信号的时域表 示，自相关函数及功率谱(Design of a signal generator and simultaneously draw the time domain representation of the signal, the autocorrelation function and the power spectrum)

用于人脸识别的LDA和PCA特征提取方法的Matlab代码，结合两个程序可以实现PCA+LDA特征提取方法。(LDA and PCA is a common methods of feature selection,These are their source code using matlab. )

RS-code performance vs BCH-code performance in a communication system.

精选了关于matlab中一些典型的案例分析，包括编程换图等。(Featured on some typical case analysis in matlab, including programming in figure.)

说明：  matlab 防真自适应滤波器（部分）考虑时变代价函数 (Matlab defense really adaptive filter (part) when considering variable cost function)

该文件为区域选择的相关程序，希望对你有所帮助(it is about area selecting)

主成分分析是把原来多个变量划为少数几个综合指标的一种统计分析方法。 从数学角度来看，这是一种降维处理技术。(Principal component analysis (PCA) is a statistical analysis method that divides a number of variables into a few comprehensive indexes.From a mathematical point of view, this is a kind of dimensionality reduction technology.)
