Scilab - Alternate instruction in scilab for filtic in matlab

Alternate instruction in scilab for filtic in matlab

Regarding use of filter instruction we have problem . The program runs well if there are no initial conditions. But we are not finding an alternative for instruction filtic ( matlab ) in scilab . Can you please help us. I have attached the codes

clc;
clear;
// Difference equation is y[n]+3y[n-1]=x[n]+x[n-1]; x[n]=(1/2)^n u[n];y(-1)=2
n = 0:3;
a =[1 3]; //left hand side of difference equation
b =[1 1]; //right hand side of difference equation
yi=[2];
xi=0;
x=(1/2).^n;
y=filter(b,a,x,yi)
plot2d3(n,y,1)
plot(n,y,'r.')

Please be more specific. Does the page not load? Are you not able to download the code? Does the toolbox not install?

Thank you Shamika, I used the function filtic provided in signal processing tool box as shown below, but i am getting error

clc;
// Difference equation is y[n]+3y[n-1]=x[n]+x[n-1]; x[n]=(1/2)^n u[n];y(-1)=2
n = 0:3;
a =[1 3]; //left hand side of difference equation
b =[1 1]; //right hand side of difference equation
y=[2];
x=0;
x=(1/2).^n;
zi=filtic(b,a,y,x);
y1=filter(b,a,x,[zi])
plot2d3(n,y1,1)
plot(n,y1,'r.')

Error
!--error 4

A lot of institutions, including government offices, non-profits, catholic churches that help with motel vouchers to assist the homeless population who has recently been exiled or had to leave their home for safety reasons, such as family violence or personal emergency situations that require temporary housing.

Thank you for this, alternative instructions are always good. In any case, I like having an alternoute route. That's one thing I learned being in the towing service industry. Can;t always do thigns the same way every time.
