这是IEEE电力系统标准14-30-57-118节点图！(This is the IEEE standard 14-30-57-118 power system node figure! )

BCH编码、译码器，支持参数化使用，从多项式生成、编码到解码，全都有。(BCH encoder decoder)

1. It is necessary you have defined on Matlab the X - data matrix. Size of matrix must be n-by-(1+p) sample=column 1, variables=column 2:p). And alpha - significance (default = 0.05). 2. For running this file it is necessary to call the rafisher function as PROFANA(X,alpha). Please see the help PROFANA. 3. Once you input the arguments, it will appears your results. ( 1.
