Hi @Ehtisham
Well, You can be a little more descriptive about what to do with this Big GUI..
What button did you press?
What happened (error/ etc)
What did not happen (and you expected it to happen..)

When pressing the "GO" button- the next error is raised:
[t, y] = ode45(@(t, y) ode_LR(t, y, Kf_L, Kb), timespan, initial_conditions);
Error using odearguments
The last entry in tspan must be different from the first entry.
Error in ode45 (line 104)
odearguments(odeIsFuncHandle,odeTreatAsMFile, solver_name, ode, tspan, y0, options, varargin);
This error is rlating to the "timespan" argument.
A small fix (altough you have to consider this) is just changing the last entry of "timespan" (vs the 1st entry of "timespan")
The next lines do not create the error...
timespan(end) = timespan(1) + 1;
[t, y] = ode45(@(t, y) ode_LR(t, y, Kf_L, Kb), timespan, initial_conditions);
