Name	Description
x	Specifies the input signal to filter. x is a real array. If x is a matrix, the filter operates on each column of x.
s	Specifies a 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].

Outputs

Name	Description
y	Returns the filtered signal.

Examples

% 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 = sosfilt(s, sin(2.3*x))
