这是我们参加深圳杯2012年D题的打孔机生产效率的问题，希望对大家有帮助。这可是很强的东西。(This is our participation in Shenzhen Cup 2012 theme punch D productivity problem, we want to help. This is strong stuff.)

ABAQUS UMAT code 适用于平面应变，轴对称的黏弹塑性线性应变硬化材料，适用于大变形。(The ABAQUS UMAT code applies to plane strain, axisymmetric viscoelastic plasticity linear strain hardening material, suitable for large deformation.)

To calculate the capacity of an AWGN channel as a function of Power per symbol

基于MATLAB_Simulink的系统仿真技术与应用大家可以学习下，很好的东西啊(MATLAB_Simulink system based on the simulation technology and application we can learn, the good thing ah)

Convert a numeric scalar to a string giving the English name of the number value (GB/US).

带通滤波，对输入的数据进行带通滤波，采样频率为实际频率的16倍，里面有关于矩阵和数据变换的程序，大家可以自己转换(Band-pass filter, the data input bandpass filter, the sampling frequency is 16 times the actual frequency, which on the matrix and data transformation process, we can convert their own)

Mitra 的数字信号处理书的matlab仿真程序。(Mitra Digital Signal Processing of matlab simulation program book.)

说明：  在分析了无刷直流电动机 (BLDCM) 数学模型的基础上,用 MAT LAB建立了无刷直流电动机控制系统的 真模型,对系统进行了仿真和分析,给出了仿真结果,验证了数学模型的有效性及控制系统设计的合理性。(The analysis of the brushless DC motor (BLDCM) based on the mathematical model, using MAT LAB established a brushless DC motor control system of the true model of the system simulation and analysis of simulation results to verify the mathematical model effectiveness and control system design is reasonable.)

matlab的数理统计工具箱，有很强的实用价值，适合当做应用学习库来进行保留(Matlab statistics toolbox, has a strong practical value, suitable for application to retain as learning library)

本代码是关于用matlab算出两路信号的相位差(the code is calculated on the use of Matlab two signals phase difference)
