matlab code for cdma

MATLAB在光学中的应用。内容包括 衍射、干涉、传输、像差等(application of Matlab in optics. diffraction, transport,etc.)

说明：  利用传播算子，进行阵列信号角度估计，运算快，不需要峰值搜索。(Use propagator conduct array signal angle estimation, fast operation, no peak search.)

分析了正弦信号分辨率问题，当采样频率相同时，点数越多，分辨率越高，频谱特性误差越小( Analysis the problem of resolution in a sinusoidal signal.When the sampling frequency is the same, the more points,the higher the resolution,and the error spectral characteristic is smaller.)

it s acode to show the MPSK modluation

说明：  Topsis Matlab function

用于SDMA排队论的MATLAB程序，主要实现食堂排队的模拟仿真(For SDMA queuing theory MATLAB program, the main canteen queue simulation to achieve)

医学图像经典预处理，matlab文件，可直接编译(Classic pre-medical images, matlab file)

2d PDE example codes

说明：  该程序基于BP神经网络编程，开发工具MATLAB用于预测(The program based on BP neural network programming, development tools, MATLAB used to predict)
