%menentukan sistem linear atau nonlinear 
x = randi(1,200,[0,100]);
%hitung sinyal 
x1 = [x 0 0]; %x1[n] = x[n+1]
x2 = [0 x 0]; %x1[n] = x[n]
x3 = [0 0 x]; %x1[n] = x[n-1]
y1 = x1 + 2*x2 - 3*x3;
y2 = 5*x1 + 2*(5*x2) - 3*(5*x3);
y3 = 5*y1;
%tentukan jumlah bilangan yang salah 
jumlah_salah = symerr(y2,y3)

Hello R.edi

If I understand you correctly you are trying to solve a system of linear equations., where x1,x2,x3 are three variables and y1,y2,y3 are three outputs of linear equations.

Below is the documentation link to solve a system of linear equations using linsolve. I hope this resolves your issue.
