function plot doesn't work with input type syms
Instead try the following
x=[-10:0.0001:10];
y=exp(x)./x;
plot(x,y);
axis([-10 10 -1e3 1e3])
grid on
title('e^x/x')
and the following doesn't crash
syms x x0;
y= exp(x-x0)/(x-x0)
x_tay4=taylor(y, 'order',4)
y =
exp(x - x0)/(x - x0)
x_tay4 =
(- exp(-x0)/(6*x0) - exp(-x0)/(2*x0^2) - exp(-x0)/x0^3 - exp(-x0)/x0^4)*x^3 + (- exp(-x0)/(2*x0) - exp(-x0)/x0^2 - exp(-x0)/x0^3)*x^2 + (- exp(-x0)/x0 - exp(-x0)/x0^2)*x - exp(-x0)/x0
