Set up and solve systems of first-order ODEs numerically. This MATLAB function converts a system of symbolic first-order differential algebraic equations (DAEs) to a MATLAB function handle acceptable as an input argument to the numerical MATLAB DAE solver ode15i. Solve a system of several ordinary differential equations in several variables by using the dsolve function, with or without initial conditions. To solve a single differential equation, see Solve Differential Equation .

I wish to get the solution where my output is x,y,z position vs. time plot(2nd derivative) as well as a dx,dy,dz velocity vs. time plot. This exercise contains the loud speaker differential equations.This video in MATLAB and Simulink ODE solvers demonstrates how to set up and solve multiple di The differential order of a DAE system is the highest differential order of its equations.

We wish to  Solve Differential Equations in Matrix Form · syms x(t) y(t) A = [1 2; -1 1]; B = [1; t]; Y = [x; y]; odes = diff(Y) == A*Y + B · odes(t) = diff(x(t), t) == x(t) + 2*y(t) + 1 diff(y(t), t)  Numerical solution. Example problem: The angle y of an undamped pendulum with a driving force sin(5 t) satisfies the differential equation.

MATLAB: Solve a system of Differential Equations with a piecewise function. This problem comes from the analysis of a vibrating system. The unknowns of the system and the piecewise function are functions of time. beta and x with one dot at the top are first order derivatives (respect to time).
