Your code works fine: (loop is superfluos though)

T=50:30:650;
S=0.005;
r=90;
Q=1;
 t=6.94*10^-5:0.0299:0.75;
u=(r^2)*S./(4.*T.*t);
if u<1
 w=-(0.5772)-(log(u))+u-(u.^2/(2*factorial(2)))+(u.^3/(3*factorial(3)))-(u.^4/(4*factorial(4)))+(u.^5/(5*factorial(5)));
else
     w=(2.718.^-u./(u)).*[(u.^2+2.334733.*u+0.250621)./(u.^2+ 3.330657.*u+1.681534)];
end
s=(Q*w./(4*3.14.*T));
d=s.
u1=u.';
