Help in using 'ezplot' !!!

clc
syms an bn a0;
syms t n;
syms x;

T = input('Enter the Time Period: ');
N = input('Enter the number of terms: ');
x = input('Enter the function: ');
f = @(t) x;

an = int(f(t).*cos(n*pi*t/T),t,-T,T)*(1/T);
bn = int(f(t).*sin(n*pi*t/T),t,-T,T)*(1/T);
a0 = int(f(t),t,-T,T)*(1/T);
y = a0;

pretty(a0);
pretty(an);
pretty(bn);

for i=1:1:N;
     y = y + subs(an, i).*cos(2*pi*i*t/T) + subs(bn, i).*sin(2*pi*i*t/T);
end
pretty(y);
eval(y)
ezplot(y)

Whenever I use eplot for plotting 'y' I get the following error....
Please hep me remove this error !!!
