discrete-time transfer function applied to vector data
[sim,out] = ld_VarVec_ztf(sim, events, in, Nvalues, H, FilterMode, vecsize)
FilterMode == 1 apply filter from left to right
FilterMode == 2 apply filter from right to left
FilterMode == 3 apply filter from left to right, flip result, filter from right to left (zero phase-shift filter)
H is a transfer function in z-domain represented by a scilab rational
in (float, vecsize) - vector input
out (float, vecsize) - vector output
Nvalues (int32) - the number of samples the filter is applied to (starting from the left side of the vector)
