本程序完成的是MATLAB平台下FIR滤波器设计的GUI界面，通过简单的输入参数，我们即可进行FIR滤波器的设计。-This procedure is done under the MATLAB platform for FIR filter design of the GUI interface, using a simple input parameters, we can carry out FIR filter design.

编程实现： 低通数字滤波器的设计, 设计一低通FIR滤波器,不错的(Programming implementation: the design of the low-pass digital filter, low pass FIR filter, good)
