消除文法的左递归，包括直接左递归和间接左递归(digui)

Three matlab-based tools have been developed for the convenient assess- ment of stability conditions for linear and nonlinear systems. The fi rst is a more helpful and defi nitive version of nyquist, which has features of automatic zooming and which displays on the real axis a numeral (‘0’, ‘1’ etc.)

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)

地震波场是指有地震波传播的空间。本程序用于计算二阶精度规则网格，二维波场模拟。(Seismic wave field refers to the space where seismic wave propagates. This program is used to calculate second-order precision regular grids and two-dimensional wave field simulation.)

有压缩感知算法两种实现方式； 包括GPSR_BB和GPSR_Basic算法 有一个demo可以用来学习，部分内容根据自己的理解加了中文注释(There are two implementations of compressed sensing algorithm. Including GPSR_BB and GPSR_Basic algorithm There is a demo that can be used for learning. Some of the contents are annotated in Chinese according to their own understanding.)
