<title>Description</title>
<para>
This is an Octave function.
This function generates a Bessel filter. The default is a Laplace space (s) filter.
The third parameter takes in high or low, the default value being low. The cutoff is pi*Wc radians.
[z,p,g] = besself(...) returns filter as zero-pole-gain rather than coefficients of the numerator and denominator polynomials.
[...] = besself(...,’z’) returns a discrete space (Z) filter. w must be less than 1.
[a,b,c,d] = besself(...) returns state-space matrices.
