How to write a mathematical function in MATLAB?

Hi All,
I want to write velocity vector in terms of its component in x, y and z direction , say V= V(t)_x i^+V(t)_y j^+V(t)_z k^. These components are functions of time.
Then I want to differentiate that function with respect to time.
How to do that ?
Any suggestion will be appreciated!
Thanks in advance.

%if true
% code
% end
syms t i j k
vx = t^2;
vy = t^3;
vz = t^4;
V = @(t) vx*i+vy*j+vz*k;
VV = diff(V,t);% differentiate
Use symbolic expressions and diff function

no the i^ and so on indicate different unit vectors along different axes.
You probably need to introduce new symbolic variables to stand in for the components, and add logic to handle raising them to various powers using mapSymType.
