Solve differential equations by using dsolve. Create these differential equations by using symbolic functions. See Create Symbolic Functions. Solve differential algebraic equations (DAEs) by first reducing their differential index to 1 or 0 using Symbolic Math Toolbox™ functions, and then using MATLAB ® solvers, such as ode15i, ode15s, or

Software used:- OCTAVE GUI Governing Equation :- This ODE represents the equation of motion of a simple pendulum with damping. `(d^2 theta)/dt^2 + b/m*(d theta)/dt + g/L*sin theta = 0` In the above equation, g = gravity in m/s2, L = length… Solving Complex Coupled Differential Equations . Learn more about differential equations, nonlinear I am wondering whether MATLAB is able to solve DIFFERENCE (recursive) equations, not differential ones. For example, difference equations as those frequently encountered in Economics. The differential equation solvers in MATLAB ® cover a range of uses in engineering and science.

In the original form of the radius equation. d (r^3)/dt = -3K* (r^3)^ (1/3)* (1-C) or the power-reduced one. dr/dt = -K/r* (1-C) <==> d (r^2)/dt = -2K* (1-C) you reach a singularity at the moment that the radius shrinks to zero like approximately r=sqrt (A-B*t), that is, the globules will have vanished in finite time. A typical approach to solving higher-order ordinary differential equations is to convert them to systems of first-order differential equations, and then solve those systems. The example uses Symbolic Math Toolbox™ to convert a second-order ODE to a system of first-order ODEs.
