how to create sin signal in matlab

说明：  matlab编写的流体计算和传热程序(Matlab 程序)(Matlab calculations prepared by the fluid and heat transfer procedures (procedures Matlab))

精通《MATLAB7》书中的实例，可以借鉴一下，很不错。(Proficient " MATLAB7" book instance, can learn about, very good.)

假定半波长间隔均匀分布线列布阵的阵元数N=16，若入射平面波为f=62.5Hz的正弦信号，信号持续时间为0.4s， 系统采样频率 =1 KHz,阵列加权为均匀加权，分别给出 a)当平面波信号分别从 0,10,20,30,40,50,60,70,80,90,100度方向入射时，指向90度的波束形成器的输出序列； b)当平面波信号分别从0:1:180度方向入射时，指向90度的波束形成器的输出序列经过平方求和后的分贝数输出（把所有181个输出绘制在同一幅图中)(Assuming N=16, f=62.5, fs=1KHz, uniform weight, and the code gives: a) 90 degree response when incidence angles are: 0: 10: 100 degrees b) 90 degree spectral response when incidence angles are: 0:1:180 degrees )

matlab pid仿真程序，采用simulink仿真，可以达到很好的仿真效果(matlab pid simulation program, using the simulink simulation, the simulation results can be achieved very good)

经验模态分解（EMD）程序，EMD主要用于信号分解。(Empirical Mode Decomposition (EMD) program, EMD is mainly used for signal decomposition.)
