说明：  用模式传输法计算多模干涉波导的模场传输,多模干涉波导参数可调(calculate the beam propagation inside MMI using mode propagation method)

SIFT匹配函数改进版（能显示匹配点序号，返回匹配点坐标），基于siftDemoV4改进。文件夹下有原SIFT关键点提取程序（非原创），原匹配函数为match，改进的匹配函数为matches，改进的匹配函数中参数distRatio和原函数效果一样。

这是模式识别中关于k均值动态聚类算法的matlab源码(This is the pattern recognition on the k-means clustering algorithm Matlab FOSS)

产生2fsk或4fsk的调制信号，可以控制带宽，中心频率，噪声，可以观察频谱(this can product signal)

tumor d seg The goal of segmentation is to simplify and/or change the representation of an image into something that is more meaningful and easier to analyze.Image segmentation is typically used to locate objects and boundaries
