I\'m using Matlab to solve a differential equation. I want to force ode45 to take constant steps, so it always increments 0.01 on the T axis while solving the equation. How
Your script does not indicate fixed-step size, It only shows that solution will be printed based on the time-step provided. Try check the solution structure of the ODE and you will realize that in fact, it uses a different timestep.
The best way to get it to use a fixed timestep is to ensure that both RelTol and AbsTol are large enough.
