Applies a second-order section filter.
y = filter_sos(s, x)
y = filter_sos(s, x, d)Legacy name: sosfilt
Input signal to filter. x is a real array. If x is a matrix, the filter operates on each column of x.
Second-order section filter. s is an L-by-6 matrix. Each row of s contains the coefficients of one second-order section as [b0 b1 b2 1 a1 a2].
% Apply filter and inverse filter s = [1 1 1 1 2 1; 1 2 1 1 1 1]; x = 0:0.01:2*pi; y = filter_sos(s, sin(2.3*x))
