This function converts series second-order sections to direct H(z) = B(z)/A(z) form.
[B] = sos2tf(sos) [B] = sos2tf(sos, g) [B,A] = sos2tf(...)
matrix of real or complex numbers
real or complex value, default value is 1
This is an Octave function. This function converts series second-order sections to direct H(z) = B(z)/A(z) form. The input is the sos matrix and the second parameter is the overall gain, default value of which is 1. The output is a vector.
