回复: 请教Matlab 数字滤波器设计
使用filter函数即可实现，filter函数的官方应用解释：y = filter(b,a,X) filters the data in vector X with the filter described by numerator coefficient vector b and denominator coefficient vector a. If a(1) is not equal to 1, filter normalizes the filter coefficients by a(1). If a(1) equals 0, filter returns an error.
