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.
