ABS function to solve the velosity of the vehicle vs the velosity of the wheels System will automatically delete the directory of debug and release, so please do not put files on these two directory.

a matlab code for calculating the lyapunov exponents for any given system

ios下，一个基于XMPP简单的的通信demo(Under ios, an XMPP-based communication simple demo)

使用单纯形算法整定pid参数的例程还可以(PID parameters tuning by simplex algorithm)

PMSM双闭环控制，速度环采用自抗扰控制，电流环PI控制(PMSM double closed loop control, speed loop using auto disturbance rejection control, current loop PI control)

采用music算法对采样的阵列信号进行处理，根据预先给定的值进行估计，采用标准差的方式进行估计。music算法性能的好坏(The music algorithm on sampled array signal processing, based on an estimated value given in advance, an estimated using standard differential manner. music algorithm performance is good or bad)

Tools for regression

自己写的广义LDPC的程序，包括编译码，其中最重要的是一码算法，用的是chase算法，有很好的性能，希望可以跟大家交流改进(Generalized LDPC write procedures, including the encoding and decoding, most important of which is a code algorithm, using a chase algorithm has good performance, hoping to improve communication with everyone)

用来计算无风险利率三次样条贴现函数的程序(No risk-free interest rate used to calculate the cubic spline function discounting)

说明：  wisper that is useful for all of the algorithms.
