About the element of Matrix in Matlab

I have a difficulty in using Matlab to create a matrix. The matrix have its element is a random function of time-varying valuable t such as Gaussian or Sin. When t changes the matrix is changed and my system will use this matrix to calculate.

My example:

A is a square matrix 3,3.

A(1,1) = 2 sin(t), A(1,2)=1 sin(t), A(1,3)= 3cos(t).
A(2,1) = 1 cos(t),A(2,2) = 3sin(t), A(2,3) = 2cos(t).
A (3,1)= 0.5sin(t),A(3,2) = 1.5sin(t),A(3,3)=3sin(t).

A will be changed when t is running. So how I can matrix A to calculate. Please help me about Matlab code. Thanks.

you can use a loop and a timer to keep updating the elements of matrix A
