Hi i need to obtain this transfer function with matlab

[LATEX]H(s)=\frac{0.7560*s^3}{(s^2+0.5704*s+1)*(s^2+0.4216*s+2.9224)*(s^2+0.1443*s+0.3422)}[/LATEX]

where the frequency parameter s is normalized with respect to ωn = 130,590 s–1.
It defines a sixth-order bandpass filter with a 1-dB equiripple passband in 12 kHz ≤ f ≤ 36 kHz.

Anyone could help me please? How can i use filter function of matlab (i.e ellip,cheby,butter) to obtain H(s)?
