Converting From A Continuous To Digital Filter [O-Matrix Function]
fc2dig(dt, numin, denin, numout, denout)
Converts a continuous filter to a digital filter, where dt is a real or double-precision
scalar specifying the time between samples, numin is a column vector
(with the same type as dt) specifying the numerator polynomial of the continuous filter,
denin is a column vector (with the same type as dt)
specifying the denominator polynomial for the continuous filter.
