Can anybody tell me how I can find solutions for a and b in these eq using matlab?
syms a b
t1 = 0.1
t2 = 0.2
b = 2 + a*exp((-(t1-1))/0.3)
a = 4 + (b - 1)*exp(-t2/0.667)

sola = solve(a)
solb = subs(b, a, sola)

I think this will not give correct solution. It should be like this
syms a b
t1 = 0.1;
t2 = 0.2;
eq1 = b == 2 + a*exp((-(t1-1))/0.3);
eq2 = a == 4 + (b - 1)*exp(-t2/0.667);
sol = solve([eq1 eq2])
sola = sol.a;
solb = sol.b;
