NonLinear-Equations-Matlab

本源码目的在于查找一幅图像中个图形的重心，基于matlab，找出重心后标记出来，并显示。(The Source aims to find an image in a graphics core, based on matlab, after the marked identify the focus, and display.)

基于MP的时间频率分布程序，该程序可以有效的将信号的时频分布显示出来(MP-based time-frequency distribution of program that can effectively time-frequency distribution of the signal displayed)

说明：  1对一段音频进行matlab双声道限时取样，并画图 2产生一段随机整数噪声，并加入到原样本中(1 on a two-channel audio matlab limited sampling, and drawing a random integer generated noise 2, and added to the original sample)

信号处理，用这个Matlab的程序可以处理信号。(filter signal)

用修正的周期图平均法对信号进行谱估计,采用汉宁窗,分段比较(spectral estimation：theory and application)
