说明：  基于Reed_Solomon算法的DataMatrix条码纠错码的研究基于Reed_Solomon算法的DataMatrix条码纠错码的研究(DataMatrix bar code based on Reed_Solomon algorithm of error-correcting codes DataMatrix bar code based Reed_Solomon algorithm of error-correcting codes)

说明：  曲波变换1，可以用来做曲波变换得到系数矩阵，其中含逆变换(curvelet Part)

对输入的语音信号进行分帧处理，低通滤波，中心削波，求自相关函数最后得到基音轨迹。(Speech input signal framing processing, low-pass filtering, center clipping, seeking autocorrelation function finally got the pitch trajectory.)

此程序和fn_DBn_2D程序是一起的，用于测试fn_DBn_2D程序的分解和重构效果，里面用到了一副典型图象：babala。(This procedure and the procedure is fn_DBn_2D together for testing procedures fn_DBn_2D effects of decomposition and reconstruction, which uses a typical image: babala.)

激光谐振腔（矩形腔，条形腔）的matlab模拟。输入相应数据即可得出仿真图案。(Laser resonator (rectangular cavity, the strip chamber) of the matlab simulation. Enter the appropriate data can be derived simulation design.)

说明：  包含matlab用到的所有数学计算，希望对大家有所帮助。(Matlab contains all the mathematical calculations used in the hope that all of you to help.)

MATLAB中实现PID控制系统的，改变输入r(k）分别为阶跃信号、三角波、方波。(MATLAB to achieve PID control system, change the input r (k) are step signal, triangle wave, square wave.)
