How do I plot an interval with this?

Hi, guys,

w = linspace(1,2,100);
p = dval(x,as,w);
plot(w,p)

I want to plot an interval by using this function.

But I got nonconformant arguments, how do i get this to work correctly?

I would appreciate it if someone could help me.

function s = dval(x, a, v)

n = length(a);
s = a(n);

for i = n-1:-1:1
  s = s *(v-x(i))+a(i);   % got errors here
end

%if true
 function S = dval(x, a, v)
n = length(a);
s = a(n);
for i = n-1:-1:1
s = s.*(v-x(i))+a(i);   % got errors here
end

Try this
