Book list: P. Prasad & R. Ravindran, “Partial Differential Equations”, This can be done using the MATLAB command dsolve. The syntax for solving this problem in MATLAB is. >> dsolve('Dx=-r*x') ans = C2*exp(-r*t). Notice that dsolve(eq, f(x), hint) -> Solve ordinary differential equation eq for function f(x) , using A change of coordinates, to r(x,y) and s(x,y), can be performed so this Lie We can solve a second order differential equation of the type: d2ydx2 + P(x)dydx We find: the first derivative is f'(x) = rerx; the second derivative is f''(x) = r2erx. 3.1 Solving Differential Equations with R · deSolve; · odeintr; · odein; · diffeqr an interface to the 'DifferentialEquations.jl' Julia package.
