数学建模 与MATLAB 全国大学生数学建模竞赛(These documents are PPT formated CUMCM MATLAB. )

This s for analysing experiments

二进制基带调制的文件，用matlab编写(Binary base-band modulation of the document, prepared by matlab)

1. Transfer function to state space model transfer function to state space A=[1 1 1] B=[1 6 11 6] [A,B,C,D]=tf2ss(num,den)

曲线拟合功能 实现曲线不同方式的拟合，为初学matlab做曲线拟合(Curve fitting function curve of different fitting )

FFT 与LZW编码算法相结合，实现压缩功能，MATLAB仿真实现(FFT LZW compress)

关于光栅计算模拟其中一部分，光栅透射率等等(Computer simulation on the part of the grating, grating transmission rates, etc.)

符合计数，用于单光子计数，当多光子到来时，统计时间(counting counting )

making exponential signal with matlab In communications, the purpose of using exponential signals instead of sinosuid ones is to use both halves of signal spectrum(Negative and Positive sides of spectrum). For example an FSK signal can not simply downconverted to DC. because its spectrum is not symmetric around its center frequency, so you should downconvert it with exponential signal( the idea of using I and Q downconverter).

说明：  粒子群算法，matlab实现，包含注释，适合新手(Particle swarm optimization, matlab implementation, including annotations, suitable for novice)
