Along with the differential equations we must provide the initial conditions. Let's put the pendulum at an initial angle of = /2, this is horizontal, and let it go from rest, so 0=0. Lets also set a few parameters. Let's take g = 9.8 m/s2 and L =1.0 m. Matlab’s tour de force is its ODE solver.

[DOC File]Shooting Method for Ordinary Differential Equations
https://info.5y1.org/differential-equations-in-matlab_1_b2a6de.html
Ordinary differential equations are given either with initial conditions or with boundary conditions. Look at the problem below. Figure 1. A cantilevered uniformly loaded beam. To find the deflection as a function of location, due to a uniform load , the ordinary differential equation that needs to be solved is (1) where. is the length of the beam,

[DOC File]Finite Difference Method for Solving Differential Equations
https://info.5y1.org/differential-equations-in-matlab_1_e33d33.html
The finite difference method is used to solve ordinary differential equations that have conditions imposed on the boundary rather than at the initial point. These problems are called boundary-value problems. In this chapter, we solve second-order ordinary differential equations of the form, (1) with boundary conditions. and (2)
