I am trying to find the equilibrium fo three different equtions.
clear all;
syms V(t) a b v1 v2 v3
time = [3.46

Volume = [0.0158

a1 = 0.4340;
b1 = 0.2158;
a2 = 0.3389;
b2 = 0.0489;
a3 = 0.2375;
b3 = 0.1179;
solB = solve ( a1*V(t)^(2/3) - b1*V(t) ==0, v1)
solL = solve (a2*V(t) - b2*V(t)^(2)==0, v2)
solG = solve(a3*V(t) - b3*V(t)*log(V(t)) ==0 , v3)
This what gives me: Stephan on 10 Nov 2020
Sorry, i can not follow. Please clarify what you want to do. What is the expected result? For what are the vectors for time and Volume? Your question is unclear to me.
