MATLAB经典的算法程序，帮助学习MATLAB(classic MATLAB program)

三电平变流器的空间矢量调制算法的m文件，输入为三相电压电流和母线电压。输出为比较寄存器的值。(M files of the three-level inverter space vector modulation algorithm, the input to the three-phase voltage and current and bus voltage. Output compare register value.)

用Matlab神经网络实现的字符识别。可借鉴于数字识别等。(Matlab neural network of character recognition.Can be for reference in digit recognition, etc.)

求素数域GF(p)中元素的逆元（可用于LTE中频域时域ZC序列的转换) 注：Matlab自带的函数gf只支持gf(2^m)，本程序p可以支持任意素数。(obtain inverse of the element of prime field GF(p))

包括随机梯度算法，相对梯度算法，DC-DC部分采用定功率单环控制，调试通过可以使用，快速扩展随机生成树算法，基于chebyshev的水声信号分析，IMC-PID是利用内模控制原理来对PID参数进行计算，有PMUSIC 校正前和校正后的比较。( Including stochastic gradient algorithm, the relative gradient algorithm, DC-DC power single-part set-loop control, Debugging can be used, Rapid expansion of random spanning tree algorithm, Based chebyshev underwater acoustic signal analysis, The IMC- PID is using the internal model control principle for PID parameters is calculated, A relatively before correction and after correction PMUSIC.)

channel estimation using least square

说明：  这是国外一本经典教材附带的程序，通信系统的matlab实现，所含例子丰富(This is a classic foreign materials attached to the procedures, communications systems to achieve matlab contains abundant examples of)

比较两个netcdf文件 1。通过添加内部ind2sub1函数remove函数依赖第三方 2。格式化文本(Description NCCMP compares two netcdf files and prints the differences. This function is useful for testing mathematical forecasting or prediction models. USAGE: NCCMP(ncfile1,ncfile2) NCCMP(ncfile1,ncfile2,tolerance,forceCompare) INPUT: ncfile1- name of the NetCDF file to compare ncfile2- name of the NetCDF file to compare tolerance- Compare numeric data using a tolerance threshold forceCompare- if false, exit when first difference is found true: continues to process all variables EXAMPLES: nccmp( old.nc , new.nc ,0.000001) nccmp( old.nc , new.nc ,[],true) FEATURES: 1. Print the differences and their locations 2. Exits when first difference is found or optionally continues to process all variables 3. User defined tolerance threshold to compare the variables TO DO: 1. Specific variable inclusion or exclusion 2. Specific attribute inclusion or exclusion 3. Option to ignore the history attribute 4. Ignore difference between v)
