Creating discrete-time model
Hello can someone help me, what am I doing wrong in writing this expression into MATLAB. How do I make the z's negative?
Here is my code:
Nd=[-8 5 4 0 -1 -3 2];
Dd=[-0.0648 -0.1134 0.6184 -1.436 1.7 -1.6 1]; P=Nd;Q=Dd; H = tf(P,Q,0.1)
Here is…

100 Point discrete grid in R
I am trying to use for loops to solve a 100 point discrete grid, but it is totally freaking out right now.
The code:
space<-c(1:100)
A<- 4
alpha<-0.3
beta<-0.98
vprime<-c(rep(0,100))
t_vj<-c(rep(0,100))
iterater<-function(space){
for(i in space){

I know how to draw bezier curves from four control points. However, even if the control points are from 2D grids, the generated points are not neccessarily in 2D grid.
Please help.
How would I generate all the discrete bezier curve cordinates for a…
