Solver can then be invoked to drive cell D17 to zero by varying B11:B14. The result is as shown in the spreadsheet along with a plot. 27.21 (a) First, the 2nd-order ODE can be reexpressed as the following system of 1st-order ODE’s. Next, we create an M-file to hold the ODEs: function dx=spring(t,y) dx=[y(2);-8*y(2)-1200*y(1)]

CDESOLVE numerical simultaneous ODE solver. CDESOLVE revised vesion 1.0.1 is a numerical ODE solver capable of solving up to 4 nonlinear simultaneous differential equations using a second order Runge-Kutta method also known as Heun's method. The purpose of CDESOLVE is to bring some of the functionality of the TI-86 to the TI-84.

For a 2nd order ODE, two integrators are needed to generate the signals y, y’. The input of the first integrator is y’’ which is then constructed by using functions of y, y’ and u according to the ODE. Initial conditions can be set for each integrator by double-clicking on the block. In this manner, one can create models for arbitrary ODEs.

In order to calculate E(t) a Matlab built in ode solver, Ode45, was used to solve for differential equation. We now consider initial conditions which are small perturbations of the exact lasing initial conditions Eo(t) = √Io , No(t) = N0: [1.30] In this case we used e(0) = very small value and n(0) = 0.

So the second-order equation can be rewritten as two first-order equations: This is the state-space representation of the second order ODE. Note that the system has two states, and the second-order ODE has been converted into a system of first-order ODEs. In this form the system can be input into a Matlab ODE solver to get the motion, i.e. x ...
