How do I plot a symbolic function of one variable for a specific set of argument values?

Say, I have a symbolic function y(x). There is no support for plotting it when x=logspace(1, 5, 101) in fplot(). How do I do it nicely?

syms y(x)
y(x) = cos(x) * exp(-x/10)
fplot(y, [10 100])
title('fplot')
X = logspace(1, 2, 101);
Y = double(subs(y, x, X));
plot(X, Y)
title('subs')
