1. ### Matlab, how to know time step size in the plot or how to get output of time stepsize

Since i am using matlab ode23s solver, it contains two matlab files . One contain the differential equations and another contains plotting and to run the m-files. The code are working perfectly. Now i want to know the time step size that is using on the plot. How can i get the output of time...
2. ### Solving Non-linear System of 3 differential eqns(Lorenz eqns) using ode23s in matlab.

I am trying to solve 3 differentail equations(Lorenz equations) using ode solver: ode23s in Matlab. Here are the 3 lorenz equations: dc/dt= alpha*I*(1-c) + c*(- k_f - k_d - k_n * s - k_p*(1-q)) ds/dt = lambda_b * c* P_C *(1-s)- lambda_r *(1-q)*s dq/dt = (1-q)* k_p * c *(P_C / P_Q)-...
