Arduino hx711库文件，在编写程序省去很大力气，很好用的头文件，大力推荐(Arduino hx711 library files, eliminating the need to write programs in a lot of effort, a good use of header files, strongly recommended)

说明：  Lowe2004年发表于IJCV的关于SIFT算法的经典论文(Lowe2004 published in IJCV' s classic paper on the SIFT algorithm)

本程序是使用MATLAB编写的，包括ASK、BPSK、EPSK、FSK、OOK、QPSK等仿真。(this procedure is the use of MATLAB, including ASK, BPSK, EPSK, FSK, OOK, QPSK, and other simulation.)

说明：  nmf盲源分离，使用欠定的方法，可以用来分离两路语音信号，人声与其他音的分离(nmf_bss.The underdetermined method can be used to separate two voice signals, human voice and other voices.)

SPFD5420A 用于测试彩色液晶，而且能够在液晶屏幕上显示不同色彩的色带(To test the SPFD5420A)

this file is about using matlab simulink.

一些好用的matlab小程序，课用于计算一些最小树图，最短路程等(Matlab small number of useful procedures, classes used to calculate some of the most small tree map, the shortest distance, etc.)

单源最短路径，MATLAB编程，用于数学建模。(Monophyletic shortest paths, MATLAB, used for mathematical modeling. )
