FILTIC Function
Sets initial conditions for filter in transposed direct-form-2.
Usage
z = FILTIC(h, y, x)
Input Parameters
h—A structure containing coefficients of the filter, h.a and h.b.
y—A vector of past outputs [ y(–1), y(–2), ... ], where any omitted values are treated as zero.
x—A vector of past inputs [ x(–1), x(–2), ... ], where any omitted values are treated as zero.
Returned Value
z—An n-element state vector associated with input x and output y, where n = max(N_ELEMENTS(h.a), N_ELEMENTS(h.b)) – 1.
