A New Method for Numerical Integration of Higher-Order Ordinary Differential Equations Without Losing the Periodic Responses

open access: yesFrontiers in Built Environment, 2021
A new numerical method is presented for the solution of initial value problems described by systems of N linear ordinary differential equations (ODEs). Using the state-space representation, a differential equation of order n > 1 is transformed into a ...
