Multiplying a matrix by a function

How can I multiply a matrix by a function of time so that my answer is a time dependent function?
For example: say u(t)=P*n(t)
n(t) is a function of time and P is a 5x5 matrix. I am trying to put this in matlab so that I can graph u(t) vs time.

Is the first dimension of the n(t) result 5? If not, how are you supposed to multiply it by P?

I am assuming P to be 5 X 5 matrix and n(t) to be 5x100. Hence, if you do the calculation
u(t) = P*n(t) , you are going to get u(t), a 5x100 matrix (same dimension of n(t)).
You can do it in a for loop
for i=1:size(n,1) u(i,:)=P(:,i).*n(i,:) end
