这不是一个标准MATLAB的函数 H = hpfilter （类型，男，氮， D0 ， n ）的创建传递函数的高通滤波器，氢，指定的类型和大小MxN 。可能的值类型， D0和N是： 理想 理想高通滤波器的截止频率D0 。 Ifsupplied ， n是被忽略。 btw 巴特沃思高通滤波器 n阶和截止D0 。 gaussn 高斯高通滤波器的截止（标准偏差） D0 。 如果提供，正被忽略。 M和N应该是偶数的密度泛函过滤。(THIS IS NOT A STANDARD MATLAB FUNCTION H = hpfilter (type,M,N,D0,n) creates the transfer function of a highpass filter, H, of the specified type and size MxN. Possible values for type, D0, and n are: ideal Ideal highpass filter with cutoff frequency D0. Ifsupplied, n is ignored. btw Butterworth highpass filter of order n, and cutoff D0. gaussn Gaussian highpass filter with cutoff (standard deviation)D0. )
