TY - JOUR T1 - Two Kinds of Important Numerical Methods for Calculating Periodic Solutions AU - JO - Journal of Information and Computing Science VL - 2 SP - 85 EP - 92 PY - 2024 DA - 2024/01 SN - 1 DO - http://doi.org/ UR - https://global-sci.org/intro/article_detail/jics/22847.html KW - AB - In this paper boundary value problem method and initial value problem method for periodic boundary value problem of ordinary differential equations are proposed. With use of these methods some numerical examples are computed by MATLAB .The numerical results show that these methods are very efficient.
