Calculation of discrete derivative in unit time (comparison with Simulink)

I need to read a sequence of digital sensor data $(x,y)$ where, $x=[0, 5, 10, 15, 20, 25, 30, ... 100]$ I want to calculate the change in x i.e. $\Delta x$. My assumption is that since it is a ...

How does MATLAB Simulink get such accurate ODE solution results?

I have a fixed-step model (0.001s) in Simulink in which a second order ODE is effectively being set up, a free spring-mass-damper system (m=2, c=0.3, k=1, x0=0, x_dot_0=4). I am studying the solvers ...

Is it allowed to use the quadratic solution formula for a differential equation

I have some trouble with a challenging fluid mechanics problem. The problem leads me to a non-linear ode 1st order. $0={\dot p_C}^2+\frac{k_1}{k_2 C}\dot p_C+\frac{p_C-p_0}{k_2C^2}$ My Idea was now ...
