ODE45 along with sym function

I have written the following code

clear all

A = sym('a',[1 3]);
b = zeros(1,3,'sym');
BT = zeros(1,1,'sym');
syms k
for i = 1:3
    b(i) = A(i) * k;
    BT = BT + b(i);
end

l = solve (BT == 1,k);

syms c
c = A.*l;
w = [1 10 100];

This gives me

c =
 
[ a1/(a1 + a2 + a3), a2/(a1 + a2 + a3), a3/(a1 + a2 + a3)]

Now I want to solve the following coupled differential equations:

How can I solve these equations in MATLAB?

Please help.
