Time-dependent derivatives of a function with vector-valued components

x = sym('x',[1 3]);
returns a vector-valued variable x=(x(1),..x(3)). I want each component to depend on the time, which for a scalar vaiebale I would get by
x = sym('x(t)');
I don't see a way to combine these two statements in order to obtain vector-valued variables where each component depends on the time.
I need this to calculate (total and partial) time derivatives of a function f(x(t)) where x=(x_1(t),..x_3(t))).
Thanks in advance.

instead of using sym use syms for defining vector valued functions with multple variables, e.g. x and t
syms 'x(t)' [1 3]
x
