Many students ask me how do I do this or that in MATLAB. So I thought why not have a small series of my next few blogs do that. In this blog, I show you how to solve a boundary value ordinary differential equation.

% Solve the ordinary differential equation
% Define x as a symbol
% The initial conditions
% The value at which y is sought at
%% DISPLAYING INPUTS
func=[‘ The ODE to be solved is ‘ ode_eqn];
iv_explain=[‘ The boundary conditions are ‘ iv_1 ‘ ‘ iv_2];
fprintf(‘ The value of y is sought at x=%g’,xval)
%% THE CODE
% Finding the solution of the ordinary differential equation
% vpa below uses variable-precision arithmetic (VPA) to compute each
% element of soln to 5 decimal digits of accuracy
%% DISPLAYING OUTPUTS
output=[‘ The solution to the ODE is ‘ char(soln)];
fprintf(‘ The value of y at x=%g is %g’,xval,value)
