代码说明：

  计算七类窗函数并给出归一化对数幅频曲线,同时也是利用窗函数法设计FIR滤波器的程序MDEFIR1所调用的子程序MWINDO(Seven kinds of window functions are calculated and normalized logarithmic amplitude-frequency curves are given. At the same time, it is also the subroutine MWINDO called by the program MDEFIR1 of designing FIR filter by using window function method.)
