why I got -INF by the following code
clear all
clc
u0=0;
alpha=0.5;%[0.1 0.3 0.5 0.6 0.66 0.9 1];
a=0; b=1;n=100;
h=(b-a)/n;
t=a:h:b;
f=@(t,u) (-u.^4) + ( gamma(2*alpha+1)./gamma(alpha+1) ).*(t.^alpha) - ...
( 2./gamma(3-alpha) ).*(t.^(2-alpha)) + (t.^(2*alpha)-t.^2).^4;
exact=@(t) t.^(2*alpha)-t.^2;
%-----a'ks---------------------------------------
a_kth=@(k) (k+1).^(1-alpha)-(k).^(1-alpha);
u_p=zeros(1,n); z_p=zeros(1,n); u=zeros(1,n);
s=0;
for i=1
u_p(i)=a_kth(i-1)*u0; %s=s+q^keval(subs(fun,xq^k));
z_p(i)=gamma(2-alpha)*( h.^alpha ) * f(t(i),u_p(i));
u(i)=u_p(i)+gamma(2-alpha)*( h.^alpha ) * f(t(i),u_p(i)+z_p(i));
end
%--------------------------------------
for i=2:n
for k=1:i-1
s=s+(a_kth(i-1-k)-a_kth(i-k))*u(k);
WW(i,k)=s;
u_p(i)=a_kth(i-1)*u0+s; %s=s+q^keval(subs(fun,xq^k));
z_p(i)=gamma(2-alpha)*( h.^alpha ) * f(t(i),u_p(i));
u(i)=u_p(i)+gamma(2-alpha)*( h.^alpha ) * f(t(i),u_p(i)+z_p(i));
end
end
u1=[ u0 u];
%plot(t,u1)
exact1=exact(t);
error=exact1-u1;

I've implemented the formula from the image again and get the same behavior for up. This means, that your output is mostlikely mathematically correct. What you you expect instead?
