zf = filtic (b, a, y) ¶zf = filtic (b, a, y, x) ¶Set initial condition vector for filter function The vector zf has the same values that would be obtained from function filter given past inputs x and outputs y
The vectors x and y contain the most recent inputs and outputs respectively, with the newest values first:
x = [x(-1) x(-2) ... x(-nb)], nb = length(b)-1 y = [y(-1) y(-2) ... y(-na)], na = length(a)-a
If length(x)<nb then it is zero padded If length(y)<na then it is zero padded
zf = filtic(b, a, y) Initial conditions for filter with coefficients a and b and output vector y, assuming input vector x is zero
zf = filtic(b, a, y, x) Initial conditions for filter with coefficients a and b input vector x and output vector y
