so what is the value of a ? it can not be a scalar.here a =1. it should be a vector or matrix

i have considered the variable with random number
t=1:20;
I=0.5;
a=randi(20,1,20);
b=randi(30,1,20);
c=randi(30,1,20);
m=1;
d=5;
r=0.0001;
s=4;
xr=-1.6;
sumx=0;
sumy=0;
sumz=0;
C=cell(1,3);
for i=1:20
C{i,1}=(-m*a(i).^3+b*a(i).^2+b(i)-c(i)+I)/(i+1);
C{i,2}=(c-d*a(i)^2-b(i))/(i+1);
C{i,3}=r*((s*(a(i)-xr)-c(i)))/(i+1);
sumx=sumx+C{i,1}.*t.^i;
sumy=sumy+C{i,2}.*t.^i;
sumz=sumz+C{i,3}.*t.^i;
end
plot(t,sumx)
